Detailed description for this pull request:
1. Update devfreq core
- Add new devfreq_frequency tracepoint to show the frequency change
information.
- Add governor feature flag. The devfreq governor is able to
have the specific flag in order to contain the non-common feature.
For example, if governor contains the 'immutable' feature, don't allow
user to change the governor via sysfs.
- Add governor sysfs attribute flag for each sysfs file. Prior to that
devfreq subsystem show the all sysfs files regardless of governor type.
But, some sysfs fils are not supported on the specific devfreq governor.
In order to show the only supported sysfs files according to the governor,
clarify the access permission of sysfs attributes according to governor.
When adding the devfreq governor, can specify the available attribute
information by using DEVFREQ_GOV_ATTR_* constant variable. The user can
read or write the sysfs attributes in accordance to the specified attributes.
- Clean-up the code to remove the duplicate code for the devfreq tracepoint
and to remove redundant governor_name field from struct devfreq
2. Update exynos-bus.c devfreq driver
- Add interconnect API support for the Samsung Exynos Bus Frequency driver
of exynos-bus.c. Complementing the devfreq driver with an interconnect
functionality allows to ensure the QoS requirements of devices accessing
the system memory (e.g. video processing devices) are fulfilled
and allows to avoid issues like the DMA underrun.
3. Update tegra devfreq driver
- Add interconnect support and OPP interface for tegra30-devfreq.c.
Also, it is to guarantee the QoS requirement of some devices like
display controller.
- Move tegra20-devfreq.c from drivers/devfreq/ into driver/memory/tegra/
in order to use the more proper monitoring feature such as EMC_STAT
which is based in driver/memory/tegra/.
- Separate the configuration information for different SoC on
tegra30-devfrqe.c. The tegra30-devfreq.c had been supported both
tegra30-actmon and tegra124-actmon devices. In order to use
the more correct configuration data, separate them.
- Use dev_err_probe() to handle the deferred probe error on tegra30-devfreq.c.
4. Pull the request of 'Tegra SoC and clock controller changes for v5.11'
sent by Krzysztof Kozlowski <krzk@kernel.org> in order to prevent the
build error.

The DMAs in AM64 have built in rings compared to AM654/J721e/J7200 where a
separate and generic ringacc is used.
The ring SW interface is similar to ringacc with some major architectural
differences, like
They are part of the DMA (BCDMA or PKTDMA).
They are dual mode rings are modeled as pair of Rings objects which has
common configuration and memory buffer, but separate real-time control
register sets for each direction mem2dev (forward) and dev2mem (reverse).
The ringacc driver must be initialized for DMA rings use with
k3_ringacc_dmarings_init() as it is not an independent device as ringacc
is.
AM64 rings must be requested only using k3_ringacc_request_rings_pair(),
and forward ring must always be initialized/configured. After this any
other Ringacc APIs can be used without any callers changes.

Driver changes for omaps for genpd for v5.11 merge window
This series of changes allows booting am335x with genpd and
device tree data without the legacy platform data. Also at
least am437x can be booted with gendp with power domain and
dts data. The SoC specific dts changes will be a separate
pull request.
We need the following driver changes merged before the dts
changes can be done:
- platform code needs a few improvments to probe l4_wkup first
for clocks, and to bail out when there is no platform data
- ti-sysc driver needs a non-urgent fix for asserting rstctrl
reset only after disabling the clocks, to probe modules with
no known control registers, and added quirk handling for gpmc
devices
- omap-prm driver needs a non-urgent fix for reset status bit,
support added for pm_clk, and then we add the rest of am335x
power domain data
- clock driver for am335x needs to keep l3_main clock enabled
with genpd for suspend and resume to work
- wkup_m3 remoteproc driver needs support added for reset
control if available instead of the legacy pdata callbacks
- pm33xx driver needs PM runtime support added for genpd
The am335x specific driver changes for the clock, wkup_m3,
pm33xx and remoteproc drivers are quite trivial and have not
caused merge conflicts in Linux next. I did not get acks for
these changes except from Santosh but had already pushed out
the branch already at that point. So I've added the related
driver maintainers to Cc.

Qualcomm driver updates for v5.11
This adds support for the core power domains on MSM8916, MSM8939, SDM660
and SDX55. It adds SM8150 support to the last-level cache controller
driver and it makes it possible to build the Command DB and RPMh drivers
as modules.
It also contains a slew of smaller cleanups, style and bug fixes
throughout the various drivers.

The Exynos ChipID driver on Exynos SoCs has only informational
purpose - to expose the SoC device in sysfs. No other drivers
depend on it so there is really no benefit of initializing it early.
Instead, initialize everything with arch_initcall which:
1. Allows to use dev_info() as the SoC bus is present (since
core_initcall),
2. Could speed things up because of execution in a SMP environment
(after bringing up secondary CPUs, unlike early_initcall),
3. Reduces the amount of work to be done early, when the kernel has to
bring up critical devices.

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.

So far most of the drivers with the MBUS quirks had to duplicate the
code to deal with DT compatibility and enforcing the DMA offsets.
Let's move for a more maintainable solution by putting everything in a
notifier that would take care of setting up the DMA offsets for all the
MBUS devices.

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.

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().

I had queued up a batch of fixes that got a bit close to the release for
sending in before the merge window opened, so I'm including them in the
batch of pull requests instead. They're mostly smaller DT tweaks and
fixes, the usual mix that we tend to have through the releases.

The avs drivers are all SoC specific drivers that doesn't share any code.
Instead they are located in a directory, mostly to keep similar
functionality together. From a maintenance point of view, it makes better
sense to collect SoC specific drivers like these, into the SoC specific
directories.
Therefore, let's move the qcom-cpr driver to the qcom directory.

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.
