93e4b3076b Char/Misc/IIO/etc driver update for 7.3-rc1
Here is the big set of char, misc, iio, counter, fpga, and other small
 driver subsystems for 7.3-rc1.
 
 Overall, due to some driver removals we only added a bit more code than
 removed, which was a nice change.  Highlights in this merge request are:
   - Loads of IIO driver updates and additions
   - binder driver updates (more on that below...)
   - Removal of the SGI XP and GRU drivers as they are not used anymore
     and turn out to be pretty insecure overall
   - Removal of the obsolete ibmasm driver as it's not being used anymore
   - Coresight driver updates and additions
   - Mei driver udpates
   - Counter driver updates
   - FPGA driver updates
   - ICC driver updates
   - lots and lots of other tiny driver updates to resolve reported
     issues
 
 All of these have been in linux-next for a while, with the only reported
 issues being some major merge conflicts.  Miguel pointed out some of
 these with the Rust tree merge, which is the majority of them.  I'll
 follow up with a diffstat of the merge resolution I made against your
 most recent tree, which works for me.

ebf1d03dab iio: inkern: Use namespaced exports
Use namespaced exports for IIO consumer API functions.

This will make it easier to manage the IIO export surface. Consumer drivers
will only be provided access to a specific set of functions, thereby
restricting usage of internal IIO functions by other parts of the kernel.

This change cannot be split into several parts without breaking
bisectability, thus all of the affected drivers are modified at once.

ASoC: stm32_sai: fix incorrect BCLK polarity for DSP_A/B, LEFT_J
The STM32 SAI driver do not set the clock strobing bit (CKSTR) for DSP_A,
DSP_B and LEFT_J formats, causing data to be sampled on the wrong BCLK
edge when SND_SOC_DAIFMT_NB_NF is used.

Per ALSA convention, NB_NF requires sampling on the rising BCLK edge.
The STM32MP25 SAI reference manual states that CKSTR=1 is required for
signals received by the SAI to be sampled on the SCK rising edge.
Without setting CKSTR=1, the SAI samples on the falling edge, violating
the NB_NF convention. For comparison, the NXP FSL SAI driver correctly
sets FSL_SAI_CR2_BCP for DSP_A, DSP_B and LEFT_J, consistent with its
I2S handling.

This patch adds SAI_XCR1_CKSTR for DSP_A, DSP_B and LEFT_J in
stm32_sai_set_dai_fmt which was verified empirically with a cs47l35 codec.
RIGHT_J (LSB) is not investigated and addressed by this patch.

Note: the STM32 I2S driver (stm32_i2s_set_dai_fmt) may have the same issue
for DSP_A mode, as I2S_CGFR_CKPOL is not set. This has not been verified
and is left for a separate investigation.

ASoC: stm32: sai: fix OF node leak on probe
The reference taken to the sync provider OF node when probing the
platform device is currently only dropped if the set_sync() callback
fails during DAI probe.

Make sure to drop the reference on platform probe failures (e.g. probe
deferral) and on driver unbind.

This also avoids a potential use-after-free in case the DAI is ever
reprobed without first rebinding the platform driver.

ASoC: stm32: dfsdm: don't use %pK through printk
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.

ASoC: stm32: sai: manage context in set_sysclk callback
The mclk direction now needs to be specified in endpoint node with
"system-clock-direction-out" property. However some calls to the
set_sysclk callback, related to CPU DAI clock, result in unbalanced
calls to clock API.
The set_sysclk callback in STM32 SAI driver is intended only for mclk
management. So it is relevant to ensure that calls to set_sysclk are
related to mclk only.
Since the master clock is handled only at runtime, skip the calls to
set_sysclk in the initialization phase.

ASoC: stm: stm32_i2s: Fix calc_clk_div() error handling in determine_rate()
calc_clk_div() will only return a non-zero value (-EINVAL)
in case of error. On the other hand, req->rate is an unsigned long.
It seems quite odd that req->rate would be assigned a negative value,
which is clearly not a rate, and success would be returned.

Reinstate previous logic, which would just return error.

AsoC: Phase out hybrid PCI devres
Merge series from Philipp Stanner <phasta@kernel.org>:

A year ago we spent quite some work trying to get PCI into better shape.
Some pci_ functions can be sometimes managed with devres, which is
obviously bad. We want to provide an obvious API, where pci_ functions
are never, and pcim_ functions are always managed.

Thus, everyone enabling his device with pcim_enable_device() must be
ported to pcim_ functions. Porting all users will later enable us to
significantly simplify parts of the PCI subsystem. See here [1] for
details.

This patch series does that for sound.

Feel free to squash the commits as you see fit.

ASoC: stm32: sai: add a check on minimal kernel frequency
On MP2 SoCs SAI kernel clock rate is managed through
stm32_sai_set_parent_rate() function.
If the kernel clock rate was set previously to a low frequency, this
frequency may be too low to support the newly requested audio stream rate.
However the stm32_sai_rate_accurate() will only check accuracy against
the maximum kernel clock rate. The function will return leaving the kernel
clock rate unchanged.
Add a check on minimal frequency requirement, to avoid this.

ASoC: stm32: sai: skip useless iterations on kernel rate loop
the frequency of the kernel clock must be greater than or equal to the
bitclock rate. When searching for a convenient kernel clock rate in
stm32_sai_set_parent_rate() function, it is useless to continue the loop
below bitclock rate, as it will result in a invalid kernel clock rate.
Change the loop output condition.

Add STM32MP25 support for STM32 I2S.

On STM32MP25 the I2S driver does not manage I2S kernel clock rate
by choosing its parent clock, depending on audio stream rate.

The driver requests a rate change on I2S kernel clock instead.
It tries to set the higher possible rate, which is a multiple of
the audio stream rate and which gives an accuracy of at least 1000 ppm.

Add STM32MP25 support for STM32 SAI.

On STM32MP25 the SAI driver does not manage SAI kernel clock rate
by chosing its parent clock, dependending on audio stream rate.

The driver requests a rate change on SAI kernel clock instead.
This rate change is performed with the following guidelines:
- Chose highest rate multiple of the audio stream
  (Try to get clock accuracy within 1000 ppm)
- Ensure clock rate compatibility between SAI sub-blocks A&B
  and between instances sharing the same flexgen.
  Use clk_rate_exclusive API to fulfill this requirement.

The STM32 SAI peripheral does not support the DMA burst mode
on STM32MP25. Add a field in compatible structure to manage DMA
burst support capability.
