the intermediate stage seems ready to merge.
Beside that Tegra 210 memory controller got few fixes and received new

Hardware issue:
- Reading register RCPM_IPPDEXPCR1 always return zero, this causes
system firmware could not get correct information and wrongly do
clock gating for all wakeup source IP during system suspend. Then
those IPs will never get chance to wake system.
Workaround:
- Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8
to allow system firmware's psci method read it and do things accordingly.

The Allwinner SoCs have a number of high-bandwidth devices connected to
a memory bus with a different RAM mapping than the CPU.
This was addressed before through drivers setting the DMA offsets
directly, and subsequently changed to calls to dma_direct_set_offset.
However that wasn't really meant to be exported to modules (and thus
drivers). The duplicated code also led to small inconsistencies across
drivers in how we dealt with DT backward compatibility.
Move all that DMA setup code into a platform bus notifier to share that
code and remove the export on dma_direct_set_offset.

The patch fix two reference leak.
1) pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to call put operation will result in
reference leak.
2) The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced.
We fix it by: 1) adding call pm_runtime_put_noidle or
pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable
in error handling, to keep usage counter and disable depth balanced.

dpaa_eth_napi_schedule() and caam_qi_napi_schedule() schedule NAPI if
invoked from:
- Hard interrupt context
- Any context which is not serving soft interrupts
Any context which is not serving soft interrupts includes hard interrupts
so the in_irq() check is redundant. caam_qi_napi_schedule() has a comment
about this:
/*
* In case of threaded ISR, for RT kernels in_irq() does not return
* appropriate value, so use in_serving_softirq to distinguish between
* softirq and irq contexts.
*/
if (in_irq() || !in_serving_softirq())
This has nothing to do with RT. Even on a non RT kernel force threaded
interrupts run obviously in thread context and therefore in_irq() returns
false when invoked from the handler.
The extension of the in_irq() check with !in_serving_softirq() was there
when the drivers were added, but in the out of tree FSL BSP the original
condition was in_irq() which got extended due to failures on RT.
The usage of in_xxx() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be
separated or the context be conveyed in an argument passed by the caller,
which usually knows the context. Right he is, the above construct is
clearly showing why.
The following callchains have been analyzed to end up in
dpaa_eth_napi_schedule():
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
portal_isr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
Both need to schedule NAPI.
The crypto part has another code path leading up to this:
kill_fq()
empty_retired_fq()
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
kill_fq() is called from task context and ends up scheduling NAPI, but
that's pointless and an unintended side effect of the !in_serving_softirq()
check.
The code path:
caam_qi_poll() -> qman_p_poll_dqrr()
is invoked from NAPI and I *assume* from crypto's NAPI device and not
from qbman's NAPI device. I *guess* it is okay to skip scheduling NAPI
(because this is what happens now) but could be changed if it is wrong
due to `budget' handling.
Add an argument to __poll_portal_fast() which is true if NAPI needs to be
scheduled. This requires propagating the value to the caller including
`qman_cb_dqrr' typedef which is used by the dpaa and the crypto driver.

In RING mode the ringacc does not access the ring memory. In this access
mode the ringacc coherency does not have meaning.
If the ring is configured in RING mode, then the ringacc itself will not
access to the ring memory. Only the requester (user) of the ring is going
to read/write to the memory.
Extend the ring configuration parameters with a device pointer to be used
for DMA API when the ring is configured in RING mode.
Extending the ring configuration struct will allow per ring selection of
device to be used for allocation, thus allowing per ring coherency.
To avoid regression, fall back to use the ringacc dev in case the alloc_dev
is not provided.

The Exynos clock output (clkout) driver uses same register address space
(Power Management Unit address space) as Exynos PMU driver and same set
of compatibles. It was modeled as clock provider instantiated with
CLK_OF_DECLARE_DRIVER().
This however brings ordering problems and lack of probe deferral,
therefore clkout driver should be converted to a regular module and
instantiated as a child of PMU driver to be able to use existing
compatibles and address space.

The functions geni_se_select_fifo_mode() and
geni_se_select_fifo_mode() are a little funny. They read/write a
bunch of memory mapped registers even if they don't change or aren't
relevant for the current protocol. Let's make them a little more
sane. We'll also add a comment explaining why we don't do some of the
operations for UART.
NOTE: there is no evidence at all that this makes any performance
difference and it fixes no bugs. However, it seems (to me) like it
makes the functions a little easier to understand. Decreasing the
amount of times we read/write memory mapped registers is also nice,
even if we are using "relaxed" variants.

On geni-i2c transfers using DMA, it was seen that if you program the
command (I2C_READ) before calling geni_se_rx_dma_prep() that it could
cause interrupts to fire. If we get unlucky, these interrupts can
just keep firing (and not be handled) blocking further progress and
hanging the system.
In commit 02b9aec592 ("i2c: i2c-qcom-geni: Fix DMA transfer race")
we avoided that by making sure we didn't program the command until
after geni_se_rx_dma_prep() was called. While that avoided the
problems, it also turns out to be invalid. At least in the TX case we
started seeing sporadic corrupted transfers. This is easily seen by
adding an msleep() between the DMA prep and the writing of the
command, which makes the problem worse. That means we need to revert
that commit and find another way to fix the bogus IRQs.
Specifically, after reverting commit 02b9aec592 ("i2c:
i2c-qcom-geni: Fix DMA transfer race"), I put some traces in. I found
that the when the interrupts were firing like crazy:
- "m_stat" had bits for M_RX_IRQ_EN, M_RX_FIFO_WATERMARK_EN set.
- "dma" was set.
Further debugging showed that I could make the problem happen more
reliably by adding an "msleep(1)" any time after geni_se_setup_m_cmd()
ran up until geni_se_rx_dma_prep() programmed the length.
A rather simple fix is to change geni_se_select_dma_mode() so it's a
true inverse of geni_se_select_fifo_mode() and disables all the FIFO
related interrupts. Now the problematic interrupts can't fire and we
can program things in the correct order without worrying.
As part of this, let's also change the writel_relaxed() in the prepare
function to a writel() so that our DMA is guaranteed to be prepared
now that we can't rely on geni_se_setup_m_cmd()'s writel().
NOTE: the only current user of GENI_SE_DMA in mainline is i2c.

This patch allow the rpmh driver to be loaded as a permenent
module. Meaning it can be loaded from a module, but then cannot
be unloaded.
Ideally, it would include a remove hook and related logic, but
the rpmh driver is fairly core to the system, so once its loaded
with almost anything else to get the system to go, the dependencies
are not likely to ever also be removed.
So making it a permanent module at least improves things slightly
over requiring it to be a built in driver.

Commit efde2659b0 ("drivers: qcom: rpmh-rsc: Use rcuidle tracepoints
for rpmh") was written to fix a bug seen in an unmerged series that
implemented a struct generic_pm_domain::power_off() callback calling
rpmh_flush(). See stack trace below.
Call trace:
dump_backtrace+0x0/0x174
show_stack+0x20/0x2c
dump_stack+0xc8/0x124
lockdep_rcu_suspicious+0xe4/0x104

rpmh_domain_power_off+0x78/0x98
_genpd_power_off+0x40/0xc0
genpd_power_off+0x168/0x208
Later the final merged solution is to use CPU PM notification to invoke
rpmh_flush() and power_off() callback of genpd is not implemented in the
driver.
CPU PM notifiers are run with RCU enabled/watching (see cpu_pm_notify()
and how it calls rcu_irq_enter_irqson() before calling the notifiers).
Remove this change since RCU will not be idle during CPU PM notifications
hence not required to use _rcuidle tracepoint. Using _rcuidle tracepoint
prevented rpmh driver to be loadable module as these are not exported
symbols.
This reverts commit efde2659b0.

Older chipsets may not be allowed to configure certain LLCC registers
as that is handled by the secure side software. However, this is not
the case for newer chipsets and they must configure these registers
according to the contents of the SCT table, while keeping in mind that
older targets may not have these capabilities. So add support to allow
such configuration of registers to enable capacity based allocation
and power collapse retention for capable chipsets.
Reason for choosing capacity based allocation rather than the default
way based allocation is because capacity based allocation allows more
finer grain partition and provides more flexibility in configuration.
As for the retention through power collapse, it has an advantage where
the cache hits are more when we wake up from power collapse although
it does burn more power but the exact power numbers are not known at
the moment.

smp2p_update_bits() should disable interrupts when it acquires its
spinlock. This is important because without the _irqsave, a priority
inversion can occur.
This function is called both with interrupts enabled in
qcom_q6v5_request_stop(), and with interrupts disabled in
ipa_smp2p_panic_notifier(). IRQ handling of spinlocks should be
consistent to avoid the panic notifier deadlocking because it's
sitting on the thread that's already got the lock via _request_stop().

The Tegra PMC driver does ungodly things with the interrupt hierarchy,
repeatedly corrupting it by pulling hwirq numbers out of thin air,
overriding existing IRQ mappings and changing the handling flow
of unsuspecting users.
All of this is done in the name of preserving the interrupt hierarchy
even when these levels do not exist in the HW. Together with the use
of proper IRQs for IPIs, this leads to an unbootable system as the
rescheduling IPI gets repeatedly repurposed for random drivers...
Instead, let's simply mark the level from which the hierarchy does
not make sense for the HW, and let the core code trim the usused
levels from the hierarchy.

Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos. This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.
The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform. The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory. However this is step forward for multiplatform or at least
to keep this code still maintainable.
This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.

Current implementation of the genpd support over TI SCI uses a single
genpd across the whole SoC, and attaches multiple devices to this. This
solution has its drawbacks, like it is currently impossible to attach
more than one power domain to a device; the core genpd implementation
requires one genpd per power-domain entry in DT for a single device.
Also, some devices like USB apparently require their own genpd during
probe time, the current shared approach in use does not work at all.
Switch the implementation over to use a single genpd per power domain
entry in DT. The domains are registered with the onecell approach, but
we also add our own xlate service due to recent introduction of the
extended flag for TI SCI PM domains; genpd core xlate service requires
a single cell per powerdomain, but we are using two cells.

The K3 J721E family of SoCs have a revised version of the PRU-ICSS (ICSSG)
processor subsystem present on K3 AM65x SoCs. These SoCs contain typically
two ICSSG instances named ICSSG0 and ICSSG1. The two ICSSGs are identical
to each other for the most part with minor SoC integration differences and
capabilities. The ICSSG1 supports slightly enhanced features like SGMII
mode Ethernet, while the ICSSG0 instance is limited to MII mode only.
There is no change in the Interrupt Controller w.r.t AM65x. All other
integration aspects are very similar to the ICSSGs on AM65x SoCs.

The K3 AM65x family of SoCs have the next generation of the PRU-ICSS
processor subsystem capable of supporting Gigabit Ethernet, and is
commonly referred to as ICSSG. These SoCs contain typically three
ICSSG instances named ICSSG0, ICSSG1 and ICSSG2. The three ICSSGs are
identical to each other for the most part with minor SoC integration
differences and capabilities. The ICSSG2 supports slightly enhanced
features like SGMII mode Ethernet, while the ICSS0 and ICSSG1 instances
are limited to MII mode only.
The ICSSGs on K3 AM65x SoCs are in general super-sets of the PRUSS on the
AM57xx/66AK2G SoCs. They include two additional auxiliary PRU cores called
RTUs and few other additional sub-modules. The interrupt integration is
also different on the K3 AM65x SoCs and are propagated through various
SoC-level Interrupt Router and Interrupt Aggregator blocks. Other IP level
differences include different constant tables, differences in system event
interrupt input sources etc. They also do not have a programmable module
reset line like those present on AM33xx/AM43xx SoCs. The modules are reset
just like any other IP with the SoC's global cold/warm resets.
The existing pruss platform driver has been updated to support these new
ICSSG instances through new AM65x specific compatibles. A build dependency
with ARCH_K3 is added to enable building all the existing PRUSS platform
drivers for this ARMv8 platform.

RAM size is larger and the number of interrupts coming into MPU INTC

The AM437x SoCs have two different PRU-ICSS subsystems: PRU-ICSS1
and a smaller PRU-ICSS0. Enhance the PRUSS platform driver to support
both the PRU-ICSS sub-systems on these SoCs.
The PRU-ICSS1 on AM437x is very similar to the PRU-ICSS on AM33xx
except for few minor differences - increased Instruction RAM, increased
Shared Data RAM2, and 1 less interrupt (PRUSS host interrupt 7 which is
redirected to the other PRUSS) towards the MPU INTC. The PRU-ICSS0 is
a cut-down version of the IP, with less DRAM per PRU, no Shared DRAM etc.
It also does not have direct access to L3 bus regions, there is a single
interface to L3 for both PRUSS0 and PRUSS1, and it would have to go
through the PRUSS1's interface. The PRUSS_SYSCFG register is reserved on
PRUSS0, so any external access requires the programming the corresponding
PRUSS_SYSCFG register in PRUSS1. It does have its own dedicated I/O lines
though. Note that this instance does not support any PRU Ethernet related
use cases.
The adaptation uses SoC-specific compatibles in the driver and uses
a newly introduced pruss_match_private_data structure and the
pruss_get_private_data() function to retrieve a PRUSS instance specific
data using a device-name based lookup logic. The reset and the L3 external
access are managed by the parent interconnect ti-sysc bus driver so that
PRUSS1 and PRUSS0 can be independently supported.

The Programmable Real-Time Unit - Industrial Communication
Subsystem (PRU-ICSS) is present on various TI SoCs such as
AM335x or AM437x or the Keystone 66AK2G. Each SoC can have
one or more PRUSS instances that may or may not be identical.
For example, AM335x SoCs have a single PRUSS, while AM437x has
two PRUSS instances PRUSS1 and PRUSS0, with the PRUSS0 being
a cut-down version of the PRUSS1.
The PRUSS consists of dual 32-bit RISC cores called the
Programmable Real-Time Units (PRUs), some shared, data and
instruction memories, some internal peripheral modules, and
an interrupt controller. The programmable nature of the PRUs
provide flexibility to implement custom peripheral interfaces,
fast real-time responses, or specialized data handling.
The PRU-ICSS functionality is achieved through three different
platform drivers addressing a specific portion of the PRUSS.
Some sub-modules of the PRU-ICSS IP reuse some of the existing
drivers (like davinci mdio driver or the generic syscon driver).
This design provides flexibility in representing the different
modules of PRUSS accordingly, and at the same time allowing the
PRUSS driver to add some instance specific configuration within
an SoC.
The PRUSS platform driver deals with the overall PRUSS and is
used for managing the subsystem level resources like various
memories and the CFG module. It is responsible for the creation
and deletion of the platform devices for the child PRU devices
and other child devices (like Interrupt Controller, MDIO node
and some syscon nodes) so that they can be managed by specific
platform drivers. The PRUSS interrupt controller is managed by
an irqchip driver, while the individual PRU RISC cores are
managed by a PRU remoteproc driver.
The driver currently supports the AM335x SoC, and support for
other TI SoCs will be added in subsequent patches.

The busy loop in rpmh_rsc_send_data() is written with the assumption
that the udelay will be preempted by the tcs_tx_done() irq handler when
the TCS slots are all full. This doesn't hold true when the calling
thread is an irqthread and the tcs_tx_done() irq is also an irqthread.
That's because kernel irqthreads are SCHED_FIFO and thus need to
voluntarily give up priority by calling into the scheduler so that other

I see RCU stalls when I boot with irqthreads on the kernel commandline
because the modem remoteproc driver is trying to send an rpmh async
message from an irqthread that needs to give up the CPU for the rpmh
irqthread to run and clear out tcs slots.

This busy loop naturally lends itself to using a wait queue so that each
thread that tries to send a message will sleep waiting on the waitqueue
and only be woken up when a free slot is available. This should make
things more predictable too because the scheduler will be able to sleep
tasks that are waiting on a free tcs instead of the busy loop we
currently have today.

The OPP core manages various resources, e.g. clocks or interconnect paths.
These resources are looked up when the OPP table is allocated once
dev_pm_opp_get_opp_table() is called the first time (either directly
or indirectly through one of the many helper functions).
At this point, the resources may not be available yet, i.e. looking them
up will result in -EPROBE_DEFER. Unfortunately, dev_pm_opp_get_opp_table()
is currently unable to propagate this error code since it only returns
the allocated OPP table or NULL.
This means that all consumers of the OPP core are required to make sure
that all necessary resources are available. Usually this happens by
requesting them, checking the result and releasing them immediately after.
For example, we have added "dev_pm_opp_of_find_icc_paths(dev, NULL)" to
several drivers now just to make sure the interconnect providers are
ready before the OPP table is allocated. If this call is missing,
the OPP core will only warn about this and then attempt to continue
without interconnect. This will eventually fail horribly, e.g.:
cpu cpu0: _allocate_opp_table: Error finding interconnect paths: -517
... later ...
of: _read_bw: Mismatch between opp-peak-kBps and paths (1 0)
cpu cpu0: _opp_add_static_v2: opp key field not found
cpu cpu0: _of_add_opp_table_v2: Failed to add OPP, -22
This example happens when trying to use interconnects for a CPU OPP
table together with qcom-cpufreq-nvmem.c. qcom-cpufreq-nvmem calls
dev_pm_opp_set_supported_hw(), which ends up allocating the OPP table
early. To fix the problem with the current approach we would need to add
yet another call to dev_pm_opp_of_find_icc_paths(dev, NULL).
But actually qcom-cpufreq-nvmem.c has nothing to do with interconnects...
This commit attempts to make this more robust by allowing
dev_pm_opp_get_opp_table() to return an error pointer. Fixing all
the usages is trivial because the function is usually used indirectly
through another helper (e.g. dev_pm_opp_set_supported_hw() above).
These other helpers already return an error pointer.
The example above then works correctly because set_supported_hw() will
return -EPROBE_DEFER, and qcom-cpufreq-nvmem.c already propagates that
error. It should also be possible to remove the remaining usages of
"dev_pm_opp_of_find_icc_paths(dev, NULL)" from other drivers as well.
Note that this commit currently only handles -EPROBE_DEFER for the
clock/interconnects within _allocate_opp_table(). Other errors are just
ignored as before. Eventually those should be propagated as well.

We must re-enable the RTC module clock enabled in RTC+DDR suspend, and
pm33xx has been using platform data callbacks for that. Looks like for
retention suspend the RTC module clock must not be re-enabled.
To remove the legacy platform data callbacks, and eventually be able to
drop the RTC legacy platform data, let's manage the RTC module clock
and register range directly in pm33xx.

Brahma-B53 and Cortex-A72 CPUs integrated on Broadcom STB SoCs feature a
read-ahead cache that performs cache line size adaptation between the
bus interface unit and the memory controller.
On 32-bit ARM kernels we have to resort to a full featured read-ahead
cache driver under arch/arm/mm/cache-b15-rac.c (CONFIG_CACHE_B15_RAC)
because there are still cache maintenance operations by set/ways/index
that cannot be transparently handled by the ARM Coherency Extension that
the read-ahead cache interfaces to.
The 64-bit ARM kernel however has long deprecated all of those, so this
is simply a one time configuration.
