To simplify with maintenance let's move the bcm power-domain drivers to the
new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.
While moving the drivers, we end up with a directory for bcm63xx that only
contains a Kconfig file, which seems a bit silly. Let's therefore also move
the Kconfig options into the Kconfig file a directory above, as it allows
us to drop the directory too.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the only effect compared to returning
zero is that the core emits an error message. By converting to
.remove_new() (which is semantically equivalent to return 0 in
.remove()) this error message is suppressed which is a good thing as
xlnx_event_manager_remove() already emits an better error message.

When tracing messages written to the RSC it's very useful to know the
type of TCS being targeted, in particular if/when the code borrows a
WAKE TCS for ACTIVE votes.
Add the "state" of the message to the traced information.
While at it, drop the "send-msg:" substring, as this is already captured
by the trace event itself.

The debugfs dump of Command DB relies uses %*pEp to print the resource
identifiers, with escaping of non-printable characters.
But p (ESCAPE_NP) does not escape NUL characters, so for identifiers
less than 8 bytes in length the output will retain these.
This does not cause an issue while looking at the dump in the terminal
(no known complaints at least), but when programmatically consuming the
debugfs output the extra characters are unwanted.
Change the fixed 8-byte sizeof() to a dynamic strnlen() to avoid
printing these NUL characters.

Since we're using these two macros to read a value from a register, we
need to use the FIELD_GET instead of the FIELD_PREP macro, otherwise
we're getting wrong values.
So instead of:
[ 3.111779] ocmem fdd00000.sram: 2 ports, 1 regions, 512 macros, not interleaved
we now get the correct value of:
[ 3.129672] ocmem fdd00000.sram: 2 ports, 1 regions, 2 macros, not interleaved

Currently we use predefined initial threshold values. This works, but
does not really scale well with more and more SoCs gaining bwmon support,
as the necessary kickoff values may differ between platforms due to memory
type and/or controller setup.
All of the data we need for that is already provided in the device tree,
anyway.
Change the thresholds to:
* low = 0 (as we've been doing up until now)
* med = high = BW_MIN
Throughput going below the med threshold nudges bwmon into signaling
that we should slow down (e.g. if we inherited too high bandwidth
from the bootloader).
Throughput going above the high threshold nudges bwmon into signaling
that we should speed up so as not to choke the bus traffic due to
insufficient transfer rates.
F_MIN is a perfect initial value for both of these cases - if we go
above it (and there's a 99.99% chance it'll happen at boot time), we
should definitely make the memory go faster, whereas if we go below it,
we should slow down, no matter what performance state we were at before
(it's only possible for them to be >= FMIN).
This only changes the values programmed at probe time, as high and med
thresholds are updated at interrupt, also based on the OPP table from DT.

More Qualcomm driver updates for v6.5
The detection of split/non-split firmware files in the MDT loader is
corrected. The Geni driver is updated to not enable unused interrupts,
in some configurations. The count unit for MSM8998 in BWMON is corrected.
RPM master stats driver is corrected to check for the right return value
of devm_ioremap().
Support for socinfo version 18 and 19 are aded, and IPQ5300 is added to
the list of platforms.

The select_fifo/dma_mode() functions in geni driver enable/disable
interrupts (secondary included) conditionally for non-uart modes, while
uart is supposed to manage this internally.
However, only uart uses secondary IRQs while spi, i2c do not care about
these at all making their enablement (or disablement) totally unnecessary
for these protos.
Similarly, select_gpi_mode() also does disable s_irq and its useless again.
Drop enabling/disabling secondary IRQs.
This doesn't solve any observed problem but only gets rid of code pieces
that are not required.

The enhanced detection introduced in commit '210d12c8197a ("soc: qcom:
mdt_loader: Enhance split binary detection")' requires that all segments
lies within the file on disk.
But the Qualcomm firmware files consistently has a BSS-like segment at
the end, with a p_offset aligned to the next 4k boundary. As the p_size
is 0 and there's nothing to load, the image is not padded to cover this
(empty) segment.
Ignore zero-sized segments when determining if the image is split, to
avoid this problem.

Move to the device-managed version of clk_notifier_register() to remove

debugfs calls should generally not be error-checked to simplify the case
where debugfs is disabled. Since this driver is built-in and has the
sysfs bind/unbind attributes disabled, it cannot be unloaded, so there
is no need to hold onto a reference to the debugfs files that are
created.
We can further simplify this by moving the debugfs file creation to a
later stage to avoid any cleanup we might have to do during error unwind
operations. This is also a little cleaner because the debugfs file
relies on data structures that are created at a later point than when
the file was previously created.

Use readl_poll_timeout_atomic() instead of open-coding the same
operation.
1. rmobile_pd_power_down(): as typically less than 20 retries are
needed, PSTR_RETRIES (100) µs is a suitable timeout value.
2. __rmobile_pd_power_up(): the old method of first polling some
cycles with a 1 µs delay, followed by more polling cycles without
any delay didn't make much sense, as the latter was insignificant
compared to the former. Furthermore, typically no retries are
needed. Hence just retain the polling with delay.

The value returned by an fsl-mc driver's remove function is mostly
ignored. (Only an error message is printed if the value is non-zero
and then device removal continues unconditionally.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Commit ebeb20a9cd ("soc: qcom: mdt_loader: Always invoke PAS
mem_setup") dropped the relocate check and made pas_mem_setup run
unconditionally. The code was later moved with commit f4e526ff7e
("soc: qcom: mdt_loader: Extract PAS operations") to
qcom_mdt_pas_init() effectively losing track of what was actually
done.
The assumption that PAS mem_setup can be done anytime was effectively
wrong, with no good reason and this caused regression on some SoC
that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that
effectively broke resulting in remoteproc silently die and ath11k not
working.
On this SoC FW relocate is not enabled and PAS mem_setup was correctly
skipped in previous kernel version resulting in correct bringup and
function of remoteproc and ath11k.
To fix the regression, reintroduce the relocate check in
qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is
not enabled.

BACKGROUND
==========
When multiple work items are queued to a workqueue, their execution order
doesn't match the queueing order. They may get executed in any order and
simultaneously. When fully serialized execution - one by one in the queueing
order - is needed, an ordered workqueue should be used which can be created
with alloc_ordered_workqueue().
However, alloc_ordered_workqueue() was a later addition. Before it, an
ordered workqueue could be obtained by creating an UNBOUND workqueue with
@max_active==1. This originally was an implementation side-effect which was
broken by 4c16bd327c ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered"). Because there were users that depended on the ordered execution,
5c0338c687 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered")
made workqueue allocation path to implicitly promote UNBOUND workqueues w/
@max_active==1 to ordered workqueues.
While this has worked okay, overloading the UNBOUND allocation interface
this way creates other issues. It's difficult to tell whether a given
workqueue actually needs to be ordered and users that legitimately want a
min concurrency level wq unexpectedly gets an ordered one instead. With
planned UNBOUND workqueue updates to improve execution locality and more
prevalence of chiplet designs which can benefit from such improvements, this
isn't a state we wanna be in forever.
This patch series audits all callsites that create an UNBOUND workqueue w/
@max_active==1 and converts them to alloc_ordered_workqueue() as necessary.
WHAT TO LOOK FOR
================
The conversions are from
alloc_workqueue(WQ_UNBOUND | flags, 1, args..)
to
alloc_ordered_workqueue(flags, args...)
which don't cause any functional changes. If you know that fully ordered
execution is not ncessary, please let me know. I'll drop the conversion and
instead add a comment noting the fact to reduce confusion while conversion
is in progress.
If you aren't fully sure, it's completely fine to let the conversion
through. The behavior will stay exactly the same and we can always
reconsider later.
As there are follow-up workqueue core changes, I'd really appreciate if the
patch can be routed through the workqueue tree w/ your acks. Thanks.

Add two new generic API pruss_cfg_read() and pruss_cfg_update() to
the PRUSS platform driver to read and program respectively a register
within the PRUSS CFG sub-module represented by a syscon driver. These
APIs are internal to PRUSS driver.
Add two new helper functions pruss_cfg_get_gpmux() & pruss_cfg_set_gpmux()
to get and set the GP MUX mode for programming the PRUSS internal wrapper
mux functionality as needed by usecases.
Various useful registers and macros for certain register bit-fields and
their values have also been added.

to a PRUSS device. This handle will be used by client drivers to
request various operations of the PRUSS platform driver through
additional API that will be added in the following patches.
The pruss_get() function returns the pruss handle corresponding
to a PRUSS device referenced by a PRU remoteproc instance. The
pruss_put() is the complimentary function to pruss_get().

The summary of the changes for this pull requests is:
* Song Liu's new struct module_memory replacement
* Nick Alcock's MODULE_LICENSE() removal for non-modules
* My cleanups and enhancements to reduce the areas where we vmalloc
module memory for duplicates, and the respective debug code which
proves the remaining vmalloc pressure comes from userspace.
Most of the changes have been in linux-next for quite some time except
the minor fixes I made to check if a module was already loaded
prior to allocating the final module memory with vmalloc and the
respective debug code it introduces to help clarify the issue. Although
the functional change is small it is rather safe as it can only *help*
reduce vmalloc space for duplicates and is confirmed to fix a bootup
issue with over 400 CPUs with KASAN enabled. I don't expect stable
kernels to pick up that fix as the cleanups would have also had to have
been picked up. Folks on larger CPU systems with modules will want to
just upgrade if vmalloc space has been an issue on bootup.
Given the size of this request, here's some more elaborate details
on this pull request.
The functional change change in this pull request is the very first
patch from Song Liu which replaces the struct module_layout with a new
struct module memory. The old data structure tried to put together all
types of supported module memory types in one data structure, the new
one abstracts the differences in memory types in a module to allow each
one to provide their own set of details. This paves the way in the
future so we can deal with them in a cleaner way. If you look at changes
they also provide a nice cleanup of how we handle these different memory
areas in a module. This change has been in linux-next since before the
merge window opened for v6.3 so to provide more than a full kernel cycle
of testing. It's a good thing as quite a bit of fixes have been found
for it.
Jason Baron then made dynamic debug a first class citizen module user by
using module notifier callbacks to allocate / remove module specific
dynamic debug information.
Nick Alcock has done quite a bit of work cross-tree to remove module
license tags from things which cannot possibly be module at my request
so to:
a) help him with his longer term tooling goals which require a
deterministic evaluation if a piece a symbol code could ever be
part of a module or not. But quite recently it is has been made
clear that tooling is not the only one that would benefit.
Disambiguating symbols also helps efforts such as live patching,
kprobes and BPF, but for other reasons and R&D on this area
is active with no clear solution in sight.
b) help us inch closer to the now generally accepted long term goal
of automating all the MODULE_LICENSE() tags from SPDX license tags
In so far as a) is concerned, although module license tags are a no-op
for non-modules, tools which would want create a mapping of possible
modules can only rely on the module license tag after the commit
8b41fc4454 ("kbuild: create modules.builtin without Makefile.modbuiltin
or tristate.conf"). Nick has been working on this *for years* and
AFAICT I was the only one to suggest two alternatives to this approach
for tooling. The complexity in one of my suggested approaches lies in
that we'd need a possible-obj-m and a could-be-module which would check
if the object being built is part of any kconfig build which could ever
lead to it being part of a module, and if so define a new define
-DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've
suggested would be to have a tristate in kconfig imply the same new
-DPOSSIBLE_MODULE as well but that means getting kconfig symbol names
mapping to modules always, and I don't think that's the case today. I am
not aware of Nick or anyone exploring either of these options. Quite
recently Josh Poimboeuf has pointed out that live patching, kprobes and
BPF would benefit from resolving some part of the disambiguation as
well but for other reasons. The function granularity KASLR (fgkaslr)
patches were mentioned but Joe Lawrence has clarified this effort has
been dropped with no clear solution in sight [1].
In the meantime removing module license tags from code which could never
be modules is welcomed for both objectives mentioned above. Some
developers have also welcomed these changes as it has helped clarify
when a module was never possible and they forgot to clean this up,
and so you'll see quite a bit of Nick's patches in other pull
requests for this merge window. I just picked up the stragglers after
rc3. LWN has good coverage on the motivation behind this work [2] and
the typical cross-tree issues he ran into along the way. The only
concrete blocker issue he ran into was that we should not remove the
MODULE_LICENSE() tags from files which have no SPDX tags yet, even if
they can never be modules. Nick ended up giving up on his efforts due
to having to do this vetting and backlash he ran into from folks who
really did *not understand* the core of the issue nor were providing
any alternative / guidance. I've gone through his changes and dropped
the patches which dropped the module license tags where an SPDX
license tag was missing, it only consisted of 11 drivers. To see
if a pull request deals with a file which lacks SPDX tags you
can just use:
./scripts/spdxcheck.py -f \
$(git diff --name-only commid-id | xargs echo)
You'll see a core module file in this pull request for the above,
but that's not related to his changes. WE just need to add the SPDX
license tag for the kernel/module/kmod.c file in the future but
it demonstrates the effectiveness of the script.
Most of Nick's changes were spread out through different trees,
and I just picked up the slack after rc3 for the last kernel was out.
Those changes have been in linux-next for over two weeks.
The cleanups, debug code I added and final fix I added for modules
were motivated by David Hildenbrand's report of boot failing on
a systems with over 400 CPUs when KASAN was enabled due to running
out of virtual memory space. Although the functional change only
consists of 3 lines in the patch "module: avoid allocation if module is
already present and ready", proving that this was the best we can
do on the modules side took quite a bit of effort and new debug code.
The initial cleanups I did on the modules side of things has been
in linux-next since around rc3 of the last kernel, the actual final
fix for and debug code however have only been in linux-next for about a
week or so but I think it is worth getting that code in for this merge
window as it does help fix / prove / evaluate the issues reported
with larger number of CPUs. Userspace is not yet fixed as it is taking
a bit of time for folks to understand the crux of the issue and find a
proper resolution. Worst come to worst, I have a kludge-of-concept [3]
of how to make kernel_read*() calls for modules unique / converge them,
but I'm currently inclined to just see if userspace can fix this
instead.

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems"
* tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (120 commits)
device property: make device_property functions take const device *
driver core: update comments in device_rename()
driver core: Don't require dynamic_debug for initcall_debug probe timing
firmware_loader: rework crypto dependencies
firmware_loader: Strip off \n from customized path
zram: fix up permission for the hot_add sysfs file
cacheinfo: Add use_arch[|_cache]_info field/function
arch_topology: Remove early cacheinfo error message if -ENOENT
cacheinfo: Check cache properties are present in DT
cacheinfo: Check sib_leaf in cache_leaves_are_shared()
cacheinfo: Allow early level detection when DT/ACPI info is missing/broken
cacheinfo: Add arm64 early level initializer implementation
cacheinfo: Add arch specific early level initializer
tty: make tty_class a static const structure
driver core: class: remove struct class_interface * from callbacks
driver core: class: mark the struct class in struct class_interface constant
driver core: class: make class_register() take a const *
driver core: class: mark class_release() as taking a const *
driver core: remove incorrect comment for device_create*
MIPS: vpe-cmp: remove module owner pointer from struct class usage.
...
At this time, it's an interesting mixture of changes for both old and
new stuff. Majority of changes are about ASoC (lots of systematic
changes for converting remove callbacks to void, and cleanups), while
we got the fixes and the enhancements of very old PCI cards, too.
Here are some highlights:
ALSA/ASoC Core:
- Continued effort of more ASoC core cleanups
- Minor improvements for XRUN handling in indirect PCM helpers
- Code refactoring of PCM core code
ASoC:
- Continued feature and simplification work on SOF, including addition
of a no-DSP mode for bringup, HDA MLink and extensions to the IPC4
protocol
- Hibernation support for CS35L45
- More DT binding conversions
- Support for Cirrus Logic CS35L56, Freescale QMC, Maxim MAX98363,
nVidia systems with MAX9809x and RT5631, Realtek RT712, Renesas R-Car
Gen4, Rockchip RK3588 and TI TAS5733
ALSA:
- Lots of works for legacy emu10k1 and ymfpci PCI drivers
- PCM kselftest fixes and enhancements

- First part of DT header detangling dropping cpu.h from of_device.h
and replacing some includes with forward declarations. A handful of
drivers needed some adjustment to their includes as a result.
- Refactor of_device.h to be used by bus drivers rather than various
device drivers. This moves non-bus related functions out of
of_device.h. The end goal is for of_platform.h and of_device.h to stop
including each other.
- Refactor open coded parsing of "ranges" in some bus drivers to use DT
address parsing functions
- Add some new address parsing functions of_property_read_reg(),
of_range_count(), and of_range_to_resource() in preparation to convert

The Oxford Semiconductor OX810/OX820 "oxnas" platform gets retired
after the ARM11MPcore processor keeps causing problems in certain corner
cases. OX820 was the only remaining SoC with this core after CNS3xxx got
retired, and its driver support for never completely merged upstream. The
Arm "Realview" reference platform still supports ARM11MPCore in principle,
but this was never a product, and the CPU support will get cleaned up
later on.
Another series updates the mv78xx0 platform, which has been similarly
neglected for a while, but should work properly again now.
The other changes are minor cleanups across platforms, mostly converting
code to more modern interfaces for DT nodes and removing some more code
as a follow-up to the large-scale platform removal in linux-6.3.

Pull ARM SoC updates from Arnd Bergmann:
"The Oxford Semiconductor OX810/OX820 'Oxnas' platform gets retired
after the ARM11MPcore processor keeps causing problems in certain
corner cases. OX820 was the only remaining SoC with this core after
CNS3xxx got retired, and its driver support was never completely
merged upstream. The Arm 'Realview' reference platform still supports
ARM11MPCore in principle, but this was never a product, and the CPU
support will get cleaned up later on.
Another series updates the mv78xx0 platform, which has been similarly
neglected for a while, but should work properly again now.
The other changes are minor cleanups across platforms, mostly
converting code to more modern interfaces for DT nodes and removing
some more code as a follow-up to the large-scale platform removal in
linux-6.3"

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

The probe function stores the sr_info pointer using
platform_set_drvdata(). Use the corresponding platform_get_drvdata() to
retrieve that pointer in the remove and shutdown functions.
This simplifies these functions and makes error handling unnecessary.
This is a good thing as at least for .remove() returning an error code
doesn't have the desired effect.
This is a preparation for making platform remove callbacks return void.

The Qualcomm SCM driver will now always clear the download bit, avoiding
entering download mode on a clean reboot because the bootloader left it
set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to
a well defined size. SM6375 support is added, and SC8180X,
QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented.
GENI gains support for newer hardware with deeper FIFOs.
The BWMON driver is updated to better handle the two register blocks,
which are not consistent between MSM8998 and newer platforms.
The LLCC driver no longer assumes a fixes stride across the various
banks, and instead acquire the bank placement from DeviceTree. EDAC
support for polling is introduced. EDAC support on SDM845 is disabled,
as its been observed that accessing relevant registers is not permitted
on most devices.
PMIC GLINK is reworked to support defining which auxiliary children to
spawn per platform, support for spawning a UCSI child is added and
SM8450 and SM8550 is introduced.
The RPM power-domain driver is cleaned up by moving and generalizing
structures that are common between platforms, rather than duplicating
everything. Macros are replaced with just direct definition of the
relevant structures. Support for defining parent relationships between
the power-domains is introduced, like it has been in rpmhpd for a long
time.
Number of processors has gone up, so max processor count in SMEM
is bumped again. Error handling in SMSM is cleaned up using
dev_err_probe().
Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150,
SA8775P and a number of PMICs.

set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to
a well defined size. SM6375 support is added, and SC8180X,
QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented.
GENI gains support for newer hardware with deeper FIFOs.
The BWMON driver is updated to better handle the two register blocks,
which are not consistent between MSM8998 and newer platforms.
The LLCC driver no longer assumes a fixes stride across the various
banks, and instead acquire the bank placement from DeviceTree. EDAC
support for polling is introduced. EDAC support on SDM845 is disabled,
as its been observed that accessing relevant registers is not permitted
on most devices.
PMIC GLINK is reworked to support defining which auxiliary children to
spawn per platform, support for spawning a UCSI child is added and
SM8450 and SM8550 is introduced.
The RPM power-domain driver is cleaned up by moving and generalizing
structures that are common between platforms, rather than duplicating
everything. Macros are replaced with just direct definition of the
relevant structures. Support for defining parent relationships between
the power-domains is introduced, like it has been in rpmhpd for a long
time.
Number of processors has gone up, so max processor count in SMEM
is bumped again. Error handling in SMSM is cleaned up using
dev_err_probe().
Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150,
SA8775P and a number of PMICs.

Microchip:
Mailbox controller & client changes for the system controller on
PolarFire SoC. The controller bits have been acked by Jassi.
Primarily the changes work around a "hardware" bug (really the system
controller's software, but it may as well be hardware as customers
cannot change it) where interrupts are not generated if a service fails.
The mailbox controller driver is tweaked to use polling, rather than
interrupt, mode and there are some changes to timeout code required in
the client driver as a result. There's some opportunistic cleanup that I
performed while doing the swap too.
Canaan:
A single fix for some randconfig issues that crop up when !mmu is
enabled for 32-bit kernels, due to my changes in a previous release that
swapped out select based entablement of the driver.

The mtk-mmsys and mutex drivers do have a dependency on MTK_CMDQ,
even though both can work with *or* without it: since CMDQ support
can be enabled either as module or as built-in, it is necessary to
add a depends rule in Kconfig, so that we disallow building both
mtk-mmsys and mtk-mutex as built-in if mtk-cmdq-helper is built as
a module, otherwise obvious linker issues appear.

Merge tag '20230407105029.2274111-4-abel.vesa@linaro.org' into drivers-for-6.4
The dedicated ICE driver was merged through a immutable tag, to make it
available to other maintainers.
This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.
The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.
So let's add the ICE dedicated driver as a soc driver.
Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.
Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.

The BWMON hardware has two sets of registers: one for the monitor itself
and one called "global". It has what seems to be some kind of a head
switch and an interrupt control register. It's usually 0x200 in size.
On fairly recent SoCs (with the starting point seemingly being moving
the OSM programming to the firmware) these two register sets are
contiguous and overlapping, like this (on sm8450):
/* notice how base.start == global_base.start+0x100 */
reg = <0x90b6400 0x300>, <0x90b6300 0x200>;
reg-names = "base", "global_base";
Which led to some confusion and the assumption that since the
"interesting" global registers begin right after global_base+0x100,
there's no need to map two separate regions and one can simply subtract
0x100 from the offsets.
This is however not the case for anything older than SDM845, as the
global region can appear in seemingly random spots on the register map.
Handle the case where the global registers are mapped separately to allow
proper functioning of BWMONv4 on MSM8998 and older. Add specific
compatibles for 845, 8280xp, 7280 and 8550 (all of which use the single
reg space scheme) to keep backwards compatibility with old DTs.

Conor Dooley <conor@kernel.org> says:
Here are some fixes for the system controller on PolarFire SoC that I
ran into while implementing support for using the system controller to
re-program the FPGA. A few are just minor bits that I fixed in passing,
but the bulk of the patchset is changes to how the mailbox figures out
if a "service" has completed.
Prior to implementing this particular functionality, the services
requested from the system controller, via its mailbox interface, always
triggered an interrupt when the system controller was finished with
the service.
Unfortunately some of the services used to validate the FPGA images
before programming them do not trigger an interrupt if they fail.
For example, the service that checks whether an FPGA image is actually
a newer version than what is already programmed, does not trigger an
interrupt, unless the image is actually newer than the one currently
programmed. If it has an earlier version, no interrupt is triggered
and a status is set in the system controller's status register to
signify the reason for the failure.
In order to differentiate between the service succeeding & the system
controller being inoperative or otherwise unable to function, I had to
switch the controller to poll a busy bit in the system controller's
registers to see if it has completed a service.
This makes sense anyway, as the interrupt corresponds to "data ready"
rather than "tx done", so I have changed the mailbox controller driver
to do that & left the interrupt solely for signalling data ready.
It just so happened that all of the services that I had worked with and
tested up to this point were "infallible" & did not set a status, so the
particular code paths were never tested.

The system controller will only deliver an interrupt if a service
succeeds. This leaves us in the unfortunate position with current code
where there is no way to differentiate between a legitimate timeout
where the service has not completed & where it has completed, but
failed.
mbox_send_message() has its own completion, and it will time out of the
system controller does not lower the busy flag. In this case, a timeout
has occurred and the error can be propagated back to the caller.
If the busy flag is lowered, but no interrupt has arrived to trigger the
rx callback, the service can be deemed to have failed. Report -EBADMSG
in this case so that callers can differentiate.

MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing
table, describing all of the possible connections between display block
components: while this is definitely working it's suboptimal for the
actual routing description, as we may be enabling outputs and inputs
that are not needed, possibly impacting on actual DDP performance other
than slightly prolonging boot times by having to parse a table that is
bigger than needed.
Seen that all of the other supported SoCs have got their own table and
seen that a comment in mtk-mmsys.h explicitly mentions that the wanted
way is to have one table per SoC, create a new routing table that is
specifically tailored to MT8173 and, while at it, remove mentions to
said SoC from the comment in mtk-mmsys.h.

The GPU core clock requires that both VDDGX and VDDMX domains are scaled
at the same rate at the same time (well, MX just before GX but you get

In some cases (like with the GPU core clock on GMU-less SoCs) it's
required that we scale more than one voltage domain. This can be achieved
by linking them in a parent-child relationship. Add support for specifying

The platforms based on SDM845 SoC locks the access to EDAC registers in the
bootloader. So probing the EDAC driver will result in a crash. Hence,
disable the creation of EDAC platform device on all SDM845 devices.
The issue has been observed on Lenovo Yoga C630 and DB845c.
While at it, also sort the members of `struct qcom_llcc_config` to avoid
any holes in-between.

Not all Qcom platforms support IRQ mode for ECC handling. For those
platforms, the current EDAC driver will not be probed due to missing ECC
IRQ in devicetree.
So add support for polling mode so that the EDAC driver can be used on all
Qcom platforms supporting LLCC.
The polling delay of 5000ms is chosen based on Qcom downstream/vendor
driver.

The Qualcomm LLCC/EDAC drivers were using a fixed register stride for
accessing the (Control and Status Registers) CSRs of each LLCC bank.
This stride only works for some SoCs like SDM845 for which driver
support was initially added.
But the later SoCs use different register stride that vary between the
banks with holes in-between. So it is not possible to use a single register
stride for accessing the CSRs of each bank. By doing so could result in a
crash.
For fixing this issue, let's obtain the base address of each LLCC bank from
devicetree and get rid of the fixed stride. This also means, there is no
need to rely on reg-names property and the base addresses can be obtained
using the index.
First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC
supports more than one bank, then those need to be defined in devicetree
for index from 1..N-1.

which will result in reduced performance. Fix that by using the slice ID
values taken from the latest LLCC SC table.

The function svs_add_device_link is called only internally from the SoC
specific probe functions. We don't need to check if the node_name is
null because that would mean that we have a buggy SoC probe function in
the first place.

As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the

The register state struct is 848 bytes, which ends up bloating the
apple_rtkit_crashlog_dump_regs stack frame beyond 1024 on some
32-bit platforms, triggering compile warnings.
This doesn't matter for 64BIT/ARM64, but there's also no good reason to
copy the structure to the stack in this case. We can use __packed to
avoid alignment issues, there are no double-read hazards, and this is a
fatal error path so performance does not matter.

The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.
Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.
SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.
The qcom_stats is changes not to fail when not all parts are

Merge tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
More Qualcomm driver updates for 6.3
The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.
Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.
SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.
The qcom_stats is changes not to fail when not all parts are
initialized.

This introduces a new driver for the Data Capture and Compare block,
which provides a mechanism for capturing hardware state (access MMIO
registers) either upon request of triggered automatically e.g. upon a
watchdog bite, for post mortem analysis.
The remote filesystem memory share driver gains support for having its
memory bound to more than a single VMID.
The SCM driver gains the minimal support needed to support a new
mechanism where secure world can put calls on hold and later request
them to be retried.
Support for the new SA8775P platform is added to rpmhpd, QDU1000 is
added to the SCM driver and a long list of platforms are added to the
socinfo driver. Support for socinfo data revision 16 is also introduced.
Lastly a driver to program the ramp controller in MSM8976 is introduced.

An $ARCH or a platform should select PM. Single device drivers
should only depend on PM, not select it.
Having SUN20I_PPU depend on PM removes a kconfig warning:

Since this device is only partially initialized by the irqchip driver,
we need to mark the fwnode device as not initialized. This is to let
fw_devlink know that the device will be completely initialized at a
later point. That way, fw_devlink will continue to defer the probe of
the power domain consumers till the power domain driver successfully
binds to the struct device and completes the initialization of the
device.

The OF_POPULATED flag was set to let fw_devlink know that the device
tree node will not have a struct device created for it. This information
is used by fw_devlink to avoid deferring the probe of consumers of this
device tree node.
Let's use fwnode_dev_initialized() instead because it achieves the same
effect without using OF specific flags. This allows more generic code to
be written in driver core.

Add support for new field coming with socinfo structure under v17 to get
hardware platform's oem variant id. This is to enable OEMs to have minor
changes in the board, but to use the same platform subtype as the one
supported by Qualcomm. The new field is to be used in platform overlay
file. Default value is 0, reserved for Qualcomm platforms. Also, add
debugfs support to read this field for a device.
