Pull sound updates from Takashi Iwai:
 "This was a relatively calm development cycle. Most of changes are
  rather small device-specific fixes and enhancements. The only
  significant changes in ALSA core are code refactoring with the recent
  cleanup infrastructure, which should bring no functionality changes.
  Some highlights below:

  Core:
   - Lots of cleanups in ALSA core code with automatic kfree cleanup and
     locking guard macros
   - New ALSA core kunit test

  ASoC:
   - SoundWire support for AMD ACP 6.3 systems
   - Support for reporting version information for AVS firmware
   - Support DSPless mode for Intel Soundwire systems
   - Support for configuring CS35L56 amplifiers using EFI calibration
     data
   - Log which component is being operated on as part of power
     management trace events.
   - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x

  HD- and USB-audio:
   - More Cirrus HD-audio codec support
   - TAS2781 HD-audio codec fixes
   - Scarlett2 mixer fixes

  Others:
   - Enhancement of virtio driver for audio control supports
   - Cleanups of legacy PM code with new macros
   - Firewire sound updates"

spi: Fix types of the last chip select storage variables

2024-03-07T15:07:10+00:00

First of all, last_cs_index_mask should be aligned with the original
cs_index_mask, which is 16-bit (for now) wide. Use the same pattern
for the last_cs_index_mask.

Second, last_cs can be negative and since 'char' is equal to 'unsigned
char' in the kernel, it's incorrect, strictly speaking, to assign
signed number to it. Use s8 type as it's done for *_native_cs ones.

With this change, regroup a bit the ordering to avoid too much memory
space to be wasted due to paddings. Shuffle kernel documentation
accordignly.

spi: add spi_optimize_message() APIs

2024-02-26T13:55:10+00:00

This adds a new spi_optimize_message() function that can be used to
optimize SPI messages that are used more than once. Peripheral drivers
that use the same message multiple times can use this API to perform SPI
message validation and controller-specific optimizations once and then
reuse the message while avoiding the overhead of revalidating the
message on each spi_(a)sync() call.

Internally, the SPI core will also call this function for each message
if the peripheral driver did not explicitly call it. This is done to so
that controller drivers don't have to have multiple code paths for
optimized and non-optimized messages.

A hook is provided for controller drivers to perform controller-specific
optimizations.

spi: gpio: Follow renaming of SPI "master" to "controller"

2024-02-09T17:26:34+00:00

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. Recent work by Uwe
completes this renaming. However, there are plenty of leftovers in
the comments and in-code documentation. Update them as well.

spi: get rid of some legacy macros

This series finishes off the removal of some of the legacy names for
SPI controllers and devices.

spi: Drop compat layer from renaming "master" to "controller"

2024-02-08T11:55:00+00:00

Now that all in-tree users followed the rename, the compat stuff can go
away.  This completes the renaming started with commit 8caab75fd2c2

spi: bitbang: Follow renaming of SPI "master" to "controller"

2024-02-08T11:54:48+00:00

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
the SPI bitbang controller drivers.

spi: drop gpf arg from __spi_split_transfer_maxsize()

2024-02-07T10:05:54+00:00

The __spi_split_transfer_maxsize() function has a gpf argument to allow
callers to specify the type of memory allocation that needs to be used.
However, this function only allocates struct spi_transfer and is not
intended to be used from atomic contexts so this type should always be
GFP_KERNEL, so we can just drop the argument.

Some callers of these functions also passed GFP_DMA, but since only
struct spi_transfer is allocated and not any tx/rx buffers, this is
not actually necessary and is removed in this commit.
