Newer SoCs with LLCC IP version 2.1.0.0 and later support write
sub-cache cacheable feature. Use a separate llcc_slice_config member
"write_scid_cacheable_en" to identify this feature and program
LLCC_TRP_SCID_WRSC_CACHEABLE_EN register to enable it.

LLCC HW version info is made up of major, branch, minor and echo
version bits each of which are 8bits. Several features in newer
LLCC HW are based on the full version rather than just major or
minor versions such as write-subcache enable which is applicable
for versions v2.0.0.0 and later, also upcoming write-subcache
cacheable for SM8450 SoC which is only present in versions v2.1.0.0
and later, so it makes it easier and cleaner to just directly
compare with the full version than adding additional major/branch/
minor/echo version checks. So remove the earlier major version check
and add full version check for those features.

Once we added support in the dpaa2-eth for driver level software TSO we
observed the following situation: if the EQCR CI (consumer index) is
read from the cache-enabled area we sometimes end up with a computed
value of available enqueue entries bigger than the size of the ring.
This eventually will lead to the multiple enqueue of the same FD which
will determine the same FD to end up on the Tx confirmation path and the
same skb being freed twice.
Just read the consumer index from the cache inhibited area so that we
avoid this situation.

This reverts commit 9de2b9286a ("ASoC: mediatek: Check for error clk
pointer").
With this patch in the tree, Chromebooks running the affected hardware
no longer boot. Bisect points to this patch, and reverting it fixes
the problem.
An analysis of the code with this patch applied shows:
ret = init_clks(pdev, clk);
if (ret)
return ERR_PTR(ret);
...
for (j = 0; j < MAX_CLKS && data->clk_id[j]; j++) {
struct clk *c = clk[data->clk_id[j]];
if (IS_ERR(c)) {
dev_err(&pdev->dev, "%s: clk unavailable\n",
data->name);
return ERR_CAST(c);
}
scpd->clk[j] = c;
}
Not all clocks in the clk_names array have to be present. Only the clocks
in the data->clk_id array are actually needed. The code already checks if
the required clocks are available and bails out if not. The assumption that
all clocks have to be present is wrong, and commit 9de2b9286a ("ASoC:
mediatek: Check for error clk pointer") needs to be reverted.

Quoting the header comments, IRQF_ONESHOT is "Used by threaded interrupts
which need to keep the irq line disabled until the threaded handler has
been run.". When applied to an interrupt that doesn't request a threaded
irq then IRQF_ONESHOT has a lesser known (undocumented?) side effect,
which it to disable the forced threading of the irq. For "normal" kernels
(without forced threading) then, if there is no thread_fn, then
IRQF_ONESHOT is a nop.
In this case disabling forced threading is not appropriate for this driver
because it calls wake_up_all() and this API cannot be called from
no-thread interrupt handlers on PREEMPT_RT systems (deadlock risk, triggers
sleeping-while-atomic warnings).
Fix this by removing IRQF_ONESHOT.

Merge tag 'sound-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"It's a relatively calm development cycle, but still lots of updates in
the driver side like Intel SOF. Below are some highlights:
ALSA / ASoC core:
- A new kselftest for ALSA control API
- PCM NO_REWINDS support
- Potential race fixes around control removals
- Unify x86 SG-buffer memory allocation code
- Cleanups and race fixes for ASoC DPCM locking
ASoC:
- Refinements and cleanups around the delay() APIs
- Wider use of dev_err_probe().
- Continuing cleanups and improvements to the SOF code
- Support for pin switches in simple-card derived cards
- Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
TLV320ADC3xxx
HD-audio / USB-audio:
- Fix deadlock at HD-audio codec unbinding
- Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
- Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
Misc:
- Fix virmidi drain behavior
Note that the merge of CS35L41 codec support is still half-baked, and
at least one ACPI change is missing. Although this won't hinder the
kernel build itself, we're going to catch up before RC1"

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top
box based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908.

The requirement to specify the active + sleep and active-only MX
power-domains as the parents of the corresponding CX power domains is
not applicable on sc7280. Fix it by using the cx/cx_ao structs for
sc7280 instead of the _w_mx_parent ones.

The rpmhpd structs were named with a SoC-name prefix, but then
they got reused across multiple SoC families making things confusing.
Rename all the struct names to remove SoC-name prefixes.
While we do this we end up with some power-domains without parents,
and some with and at times different parents across SoCs.
use a _w_<parent-name>_parent suffix for such cases.
No functional change as part of this patch.

Not all RPM firmware versions have the dynamic sleep stats offset
available. Most older versions use a fixed offset of 0xdba0.
Add support for this using new SoC-specific compatibles for APQ8084,
MSM8226, MSM8916 and MSM8974.
Even older SoCs seem to use a different offset and stats format.
If needed those could be supported in the future by adding separate
compatibles for those with a different stats_config.

1. Exynos ChipID: add Exynos7885 support.
2. Exynos PMU: add Exynos850 support.
3. Minor bindings cleanup.
4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
a shared IP block between I2C, UART/serial and SPI. Basically one has
to choose which feature the USI block will support and later the
regular I2C/serial/SPI driver will bind and work.
This merges also one commit with dt-binding headers from my dts64
pull request.
Together with a future serial driver change, this will break the ABI.
Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards
Why: To properly and efficiently support the USI with new hierarchy
of USI-{serial,SPI,I2C} devicetree nodes.
Rationale:
Recently added serial and USI support was short-sighted and did not
allow to smooth support of other features (SPI and I2C). Adding
support for USI-SPI and USI-I2C would effect in code duplication.
Adding support for different USI versions (currently supported is
USIv2 but support for v1 is planned) would cause even more code
duplication and create a solution difficult to maintain.
Since USI-serial and ExynosAutov9 have been added recently, are
considered fresh development features and there are no supported
products using them, the code/solution is being refactored in
non-backwards compatible way. The compatibility is not broken yet.
It will be when serial driver changes are accepted.
The ABI break was discussed with only known users of ExynosAutov9 and
received their permission.

drivers: Changes for v5.17-rc1
This is an assortment of driver patches that rely on some of the changes
in the for-5.17/soc branch. These have all been acked by the respective
maintainers and go through the Tegra tree to more easily handle the
build dependency.

USIv2 IP-core is found on modern ARM64 Exynos SoCs (like Exynos850) and
provides selectable serial protocol (one of: UART, SPI, I2C). USIv2
registers usually reside in the same register map as a particular
underlying protocol it implements, but have some particular offset. E.g.
on Exynos850 the USI_UART has 0x13820000 base address, where UART
registers have 0x00..0x40 offsets, and USI registers have 0xc0..0xdc
offsets. Desired protocol can be chosen via SW_CONF register from System
Register block of the same domain as USI.
Before starting to use a particular protocol, USIv2 must be configured
properly:
1. Select protocol to be used via System Register
2. Clear "reset" flag in USI_CON
3. Configure HWACG behavior (e.g. for UART Rx the HWACG must be
disabled, so that the IP clock is not gated automatically); this is
done using USI_OPTION register
4. Keep both USI clocks (PCLK and IPCLK) running during USI registers
modification
This driver implements the above behavior. Of course, USIv2 driver
should be probed before UART/I2C/SPI drivers. It can be achieved by
embedding UART/I2C/SPI nodes inside of the USI node (in Device Tree);
driver then walks underlying nodes and instantiates those. Driver also
handles USI configuration on PM resume, as register contents can be lost
during CPU suspend.
This driver is designed with different USI versions in mind. So it
should be relatively easy to add new USI revisions to it later.

The Tegra PMC driver implements a restart handler that supports Tegra
specific reboot commands such as placing the device into 'recovery' mode
in order to reprogram the platform. This is accomplished by setting the
appropriate bit in the PMC scratch0 register prior to rebooting the
platform.
For Tegra platforms that support PSCI or EFI, the default Tegra restart
handler is not called and the PSCI or EFI restart handler is called
instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra
specific reboot commands do not currently work. Fix this by moving the
code that programs the PMC scratch0 register into a separate reboot
notifier that will always be called on reboot.

2 warnings generated.
The motivation for the warning is that logical operations short circuit
while bitwise operations do not.
In this instance, tegra_fuse_read_spare() is not semantically returning
a boolean, it is returning a bit value. Use u32 for its return type so
that it can be used with either bitwise or boolean operators without any
warnings.

At the moment, using the ARM32 multi_v7_defconfig always results in two
SoCs being exposed in sysfs. This is wrong, as far as I'm aware the
Qualcomm DragonBoard 410c does not actually make use of a i.MX SoC. :)

This happens because imx_soc_device_init() registers the soc device
unconditionally, even when running on devices that do not make use of i.MX.
Arnd already reported this more than a year ago and even suggested a fix
similar to this commit, but for some reason it was never submitted.
Fix it by checking if the "__mxc_cpu_type" variable was actually
initialized by earlier platform code. On devices without i.MX it will
simply stay 0.

PM_INIT_FINALIZE tells the PMU FW that Linux is able to handle the power
management nodes that are provided by the PMU FW. Nodes that are not
requested are shut down after this call.
Calling PM_INIT_FINALIZE from the zynqmp_power driver is wrong. The PM
node request mechanism is implemented in the zynqmp_pm_domains driver,
which must also call PM_INIT_FINALIZE.
Due to the behavior of the PMU FW, all devices must be powered up before
PM_INIT_FINALIZE is called, because otherwise the devices might
misbehave. Calling PM_INIT_FINALIZE from the sync_state device callback
ensures that all users probed successfully before the PMU FW is allowed
to power off unused domains.

Implements genpd and reset providers for downstream devices. Each
instance of the driver binds to a single register and represents a
single SoC power domain.
The driver does not currently implement all features (clockgate-only
state, misc flags), but we declare the respective registers for
documentation purposes. These features will be added as they become
useful for downstream devices.
This also creates the apple/soc tree and Kconfig submenu.

With Xilinx Event Management driver, all types of events like power and
error gets handled from single place as part of event management driver.
So power events(SUSPEND_POWER_REQUEST and SUSPEND_SYSTEM_SHUTDOWN)
also gets handled by event management driver instead of zynqmp_power
driver.
zynqmp-power driver use event management driver and provide callback
function for Suspend and shutdown handler, which will be called by event
management driver when respective event is arrived.
If event management driver is not available than use ipi-mailbox rx channel
or IPI interrupt IRQ handler for power events (suspend/shutdown) same as
current zynqmp-power driver.

Xilinx event management driver provides an interface to subscribe or
unsubscribe for the event/callback supported by firmware. An agent can use
this driver to register for Error Event, Device Event and Suspend callback.
This driver only allows one agent per event to do registration. Driver will
return an error in case of multiple registration for the same event.
This driver gets notification from firmware through TF-A as SGI. During
initialization, event manager driver register handler for SGI used for
notification. It also provides SGI number info to TF-A by using
IOCTL_REGISTER_SGI call to TF-A.
After receiving notification from firmware, the driver makes an SMC call to
TF-A to get IPI data. From the IPI data provided by TF-A, event manager
identified the cause of event and forward that event/callback notification
to the respective subscribed driver. After this, in case of Error Event,
driver performs unregistration as firmware expecting from agent to do
re-registration if the agent wants to get notified on the second occurrence
of an error event.
Add new IOCTL id IOCTL_REGISTER_SGI = 25 which is used to register SGI on
TF-A.
Older firmware doesn't have all required support for event handling which
is required by the event manager driver. So add check for the register
notifier version in the event manager driver.
Xilinx event management driver provides support to subscribe for multiple
error events with the use of Event Mask in a single call of
xlnx_register_event(). Agent driver can provide 'Event' parameter value as
ORed of multiple event masks to register single callback for multiple
events. For example, to register callback for event=0x1 and event=0x2 for
the given node, agent can provide event=0x3 (0x1 | 0x2). It is not possible
to register multiple events for different nodes in a single registration
call.
Also provide support to receive multiple error events as in single
notification from firmware and then forward it to subscribed drivers via
registered callback one by one.

Currently renesas_soc_init() scans the whole device tree up to three
times, to find a device node describing a product register.
Furthermore, the product register handling for the different variants is
very similar, with the major difference being the location of the
product bitfield inside the product register.
Reduce scanning to a single pass using of_find_matching_node_and_match()
instead. Switch to a common handling of product registers, by storing
the intrinsics of each product register type in the data field of the
corresponding match entry.

This is likely due to another quirk of the GPC block. This situation can be
prevented by always synchronously powering off both the domain and MIX domain.
Make it so. This turns the aforementioned sequence into:

Pull exit cleanups from Eric Biederman:
"While looking at some issues related to the exit path in the kernel I
found several instances where the code is not using the existing
abstractions properly.
This set of changes introduces force_fatal_sig a way of sending a
signal and not allowing it to be caught, and corrects the misuse of
the existing abstractions that I found.
A lot of the misuse of the existing abstractions are silly things such
as doing something after calling a no return function, rolling BUG by
hand, doing more work than necessary to terminate a kernel thread, or
calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL).
In the review a deficiency in force_fatal_sig and force_sig_seccomp
where ptrace or sigaction could prevent the delivery of the signal was
found. I have added a change that adds SA_IMMUTABLE to change that
makes it impossible to interrupt the delivery of those signals, and
allows backporting to fix force_sig_seccomp
And Arnd found an issue where a function passed to kthread_run had the
wrong prototype, and after my cleanup was failing to build."

Pull sound updates from Takashi Iwai:
"Lots of code development have been see in ASoC side as usual, while
the continued development on memalloc helper and USB-audio low-
latency support are found in the rest.
Note that a few changes in the unusual places like arch/sh are
included, which are a part of ASoC DAI format cleanups.
ALSA core:
- Continued memalloc helper updates and cleanups, now supporting
non-coherent and non-contiguous pages
- Fixes for races in mixer OSS layer
ASoC:
- A new version of the audio graph card which supports a wider range
of systems

ARM_QCOM_SPM_CPUIDLE can be selected when compile-testing on
other architectures, but this causes a Kconfig warning

This introduces the Qualcomm "sleep stats" driver, which aids the
efforts of bringing various Qualcomm platforms into low power mode.
The SMP2P driver gains support for negotiating the "SSR" feature, which
is used to better synchronize some corner cases that might appear as the
remoteproc is recovering from a crash.
The socinfo driver learns about a few new PMICs.
SMEM is updated so that it's possible to put the compatible property
directly in the reserved-memory node, to avoid having to have a separate

Lastly it fixes some bugs in smp2p, apr, rpmhpd drivers, notably
avoiding the issue where powering on a power-domain using rpmhpd while
keeping the performance_state at 0 is a nop

This patch adds feature negotiation and ssr ack feature between
local host and remote processor. Local host can negotiate on common
features supported with remote processor.
When ssr ack feature bit is set, the remote processor will tell local
host when it is reinitialized. All clients registered for falling edge
interrupts will be notified when the smp2p entries are cleared for ssr.

The general expectation is that powering on a power-domain should make
the power domain deliver some power, and if a specific performance state
is needed further requests has to be made.
But in contrast with other power-domain implementations (e.g. rpmpd) the
RPMh does not have an interface to enable the power, so the driver has
to vote for a particular corner (performance level) in rpmh_power_on().
But the corner is never initialized, so a typical request to simply
enable the power domain would not actually turn on the hardware. Further
more, when no more clients vote for a performance state (i.e. the
aggregated vote is 0) the power domain would be turned off.
Fix both of these issues by always voting for a corner with non-zero
value, when the power domain is enabled.
The tracking of the lowest non-zero corner is performed to handle the
corner case if there's ever a domain with a non-zero lowest corner, in
which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state()
would be allowed to use this lowest corner.

interrupt scheme, a high interrupt rate has been noted for moderate
traffic flows leading to high CPU utilization.
The dpio driver exports new functions to enable/disable adaptive IRQ
coalescing on a DPIO object, to query the state or to update Net DIM
with a new set of bytes and frames dequeued.

In DPAA2 based SoCs, the IRQ coalesing support per software portal has 2
configurable parameters:
- the IRQ timeout period (QBMAN_CINH_SWP_ITPR): how many 256 QBMAN
cycles need to pass until a dequeue interrupt is asserted.
- the IRQ threshold (QBMAN_CINH_SWP_DQRR_ITR): how many dequeue
responses in the DQRR ring would generate an IRQ.
Add support for setting up and querying these IRQ coalescing related
parameters.

Through the dpio_get_attributes() firmware call the dpio driver has
access to the QBMAN clock frequency. Extend the structure which holds
the firmware's response so that we can have access to this information.
This will be needed in the next patches which also add support for
interrupt coalescing which needs to be configured based on the
frequency.

Add chip-id support for Exynos850 SoC. Despite its "E3830" ID, the
actual SoC name is Exynos850 (Exynos3830 name is internal and outdated).

Old Exynos SoCs have both Product ID and Revision ID in one single
register, while new SoCs tend to have two separate registers for those
IDs. Implement handling of both cases by passing Revision ID register
offsets in driver data.
Previously existing macros for Exynos4210 (removed in this patch) were
incorrect:
#define EXYNOS_SUBREV_MASK (0xf << 4)
#define EXYNOS_MAINREV_MASK (0xf << 0)
Actual format of PRO_ID register in Exynos4210 (offset 0x0):
[31:12] Product ID
[9:8] Package information
[7:4] Main Revision Number
[3:0] Sub Revision Number
This patch doesn't change the behavior on existing platforms, so
'/sys/devices/soc0/revision' will show the same string as before.

Practically all modern Qualcomm platforms has a single reserved-memory
region for SMEM. So rather than having to describe SMEM in the form of a
node with a reference to a reserved-memory node, allow the SMEM device
to be instantiated directly from the reserved-memory node.
The current means of falling back to dereferencing the "memory-region"
is kept as a fallback, if it's determined that the SMEM node is a
reserved-memory node.
The "qcom,smem" compatible is added to the reserved_mem_matches list, to
allow the reserved-memory device to be probed.
In order to retain the readability of the code, the resolution of
resources is split from the actual ioremapping.

This drops the use of power-domains for exposing the load_state from the
QMP driver to clients, to avoid issues related to system suspend.
SMP2P becomes wakeup capable, to allow dying remoteprocs to wake up
Linux from suspend to perform recovery.
It adds RPM power-domain support for SM6350 and MSM8953 and base RPM
support for MSM8953 and QCM2290.
It adds support for MSM8996, SDM630 and SDM660 in the SPM driver, which
will enable the introduction of proper voltage scaling of the CPU
subsystem.
Support for releasing secondary CPUs on MSM8226 is introduced.
The Asynchronous Packet Router (APR) driver is extended to support the
new Generic Packet Router (GPR) variant, which is used to communicate
with the firmware in the new AudioReach audio driver.
Lastly it transitions a number of drivers to safer string functions, as
well as switching things to use devm_platform_ioremap_resource().

for boot time hangs that can happen on some am335x devices that started
when the pruss devicetree nodes were added. The other fixes are less

- Fix external abort for am335x pruss as otherwise some am335x will hang
- Use CLKDM_NOAUTO quirk also for dra7 dcan1

This adds a driver for the blk-ctrl blocks found in the i.MX8M* line of
SoCs. The blk-ctrl is a top-level peripheral located in the various *MIX
power domains and interacts with the GPC power controller to provide the
peripherals in the power domain access to the NoC and ensures that those
peripherals are properly reset when their respective power domain is
brought back to life.
Software needs to do different things to make the bus handshake happen
after the GPC *MIX domain is powered up and before it is powered down.
As the requirements are quite different between the various blk-ctrls
there is a callback function provided to hook in the proper sequence.
The peripheral domains are quite uniform, they handle the soft clock
enables and resets in the blk-ctrl address space and sequencing with the
upstream GPC power domains.

Our usage of runtime PM to control the hierarchy of power domains is
slightly unusual and means that powering up a domain may fail in early
system resume, as runtime PM is still disallowed at this stage.
However the system suspend/resume path takes care of powering down/up
the power domains in the order defined by the device parent/child and
power-domain provider/consumer hierarachy. So we can just runtime
resume all our power-domain devices to allow the power-up to work
properly in the resume path. System suspend will still disable all
domains as intended.

To bring up the MX8MM GPU domain, it is necessary to configure both

configured when bringing up the GPU domain. This fixes the sporadic

There is currently the MX8MM GPU domain, which is in fact a composite domain
for both GPU2D and GPU3D. To correctly configure this domain, it is necessary
to control both GPC_PGC_nCTRL(GPU_2D) and GPC_PGC_nCTRL(GPU_3D) at the same
time. This is currently not possible.
Turn the domain->pgc from value into bitfield and use for_each_set_bit() to
iterate over all bits set in domain->pgc when configuring GPC_PGC_nCTRL
register array. This way it is possible to configure all GPC_PGC_nCTRL
registers required in a particular domain.

Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000

reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.

Qualcomm Generic Packet router aka GPR is the IPC mechanism found
in AudioReach next generation signal processing framework to perform
command and response messages between various processors.
GPR has concepts of static and dynamic port, all static services like
APM (Audio Processing Manager), PRM (Proxy resource manager) have
fixed port numbers where as dynamic services like graphs have dynamic
port numbers which are allocated at runtime. All GPR packet messages
will have source and destination domain and port along with opcode
and payload.

APR and other packet routers like GPR are pretty much same and
interact with other drivers in similar way.
Ex: GPR ports can be considered as APR services, only difference
is they are allocated dynamically.
Other difference is packet layout, which should not matter
with the apis abstracted. Apart from this the rest of the
functionality is pretty much identical across APR and GPR.
Make the apr code more reusable by abstracting it service level,
rather than device level so that we do not need to write
new drivers for other new packet routers like GPR.
This patch is in preparation to add GPR support to this driver.
