Implement I2C bus recovery support for the RIIC controller by making use
of software-controlled SCL and SDA line manipulation. The controller allows
forcing SCL and SDA levels through control bits, which enables generation
of manual clock pulses and a stop condition to free a stuck bus.
This implementation wires up the bus recovery mechanism using
i2c_generic_scl_recovery and provides get/set operations for SCL and SDA.
This allows the RIIC driver to recover from bus hang scenarios where SDA
is held low by a slave.

The hardware (supposedly) has a 25ms timeout for clock stretching
and the driver uses 100ms which should be plenty.
The interrupt path however misses handling for errors while waiting for
the completion and the polling path uses an open-coded readx_poll_timeout.
Note that we drop reg_write(smbus, REG_SMSTA, status) while fixing those
issues here which will be done anyway whenever the next transaction starts
via pasemi_smb_clear.

The I2C bus can get stuck under some conditions (desync between
controller and device). The pasemi controllers include an unjam feature
that is enabled on reset, but was being disabled by the driver. Keep it
enabled by explicitly setting the UJM bit in the CTL register. This
should help recover the bus from certain conditions, which would
otherwise remain stuck forever.

Add functions to perform block read and write operations. This applies
for cases where the requested operation is for >8 bytes of data.
When not using the block mode transfer, the driver will attempt a series
of 8 byte i2c operations until it reaches the desired total. For
example, for a 40 byte request the driver will complete 5 separate
transactions. This results in large transactions taking a significant
amount of time to process.
Add block mode such that the driver can request larger transactions, up
to 1024 bytes per transfer.
Many aspects of the block mode transfer is common with the regular 8
byte operations. Use generic functions for parts of the message
construction and sending the message. The key difference for the block
mode is the usage of separate FIFO buffer to store data.
Write to this buffer in the case of a write (before command send).
Read from this buffer in the case of a read (after command send).
Data is written into this buffer by placing data into the MSB onwards.
This means the bottom 8 bits of the data will match the top 8 bits, and
so on and so forth.
Set specific bits in message for block mode, enable block mode transfers
from global i2c management registers, construct message, send message,
read or write from FIFO buffer as required.
The block-mode transactions result in a significant speed increase in
large i2c requests.

The PCC driver now handles mapping and unmapping of shared memory
areas as part of pcc_mbox_{request,free}_channel(). Without these before,
this xgene-slimpro I2C driver did handling of those mappings like several
other PCC mailbox client drivers.
There were redundant operations, leading to unnecessary code. Maintaining
the consistency across these driver was harder due to scattered handling
of shmem.
Just use the mapped shmem and remove all redundant operations from this
driver.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"A handful small fixes. The only significant change is the fix for MIDI
2.0 UMP handling in ALSA sequencer, but as MIDI 2.0 stuff is still new
and rarely used, the impact should be pretty limited.
Other than that, quirks for USB-audio and a few cosmetic fixes and
changes in drivers that should be safe to apply"
* tag 'sound-6.15-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
ALSA: usb-audio: Add sample rate quirk for Microdia JP001 USB Camera
ALSA: es1968: Add error handling for snd_pcm_hw_constraint_pow2()
ALSA: sh: SND_AICA should depend on SH_DMA_API
ALSA: usb-audio: Add sample rate quirk for Audioengine D1
ALSA: ump: Fix a typo of snd_ump_stream_msg_device_info
ALSA/hda: intel-sdw-acpi: Correct sdw_intel_acpi_scan() function parameter
