The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the sta350 driver to use the more modern data structure.

This set of patches adds support for using the CS35L56 boosted smart
amplifier on HDA systems. In these systems the CS35L56 audio is
routed through a HDA-to-I2S bridge codec.
This doesn't include the changes to the Realtek driver to actually hook
up the CS35L56 driver, because we don't yet have the QUIRK IDs to
associate it with. But we want to publish the driver now so that it is
available for bringing up hardware with the CS35L56.
The first 9 patches are moving code out of the ASoC driver and into the
shared library so that it can be shared with the HDA driver.
Patch #10 fixes missing #includes in the HDA headers so that the CS35L56
driver doesn't have to #include headers that it doesn't use.
The LPASS macro drivers all acquire a number of clocks, but give no
indication when clk_get() fails, making it hard to identify and debug
system configuration issues. Make these drivers provide useful debug
information when this happens.

The audio codec typically used for the MSM8916 SoC is split into two
parts: the digital codec is part of the SoC, while the analog codec is
part of the PM8916 PMIC.
The analog codec in the PMIC has no direct connection to the mclk of
the SoC (GCC_CODEC_DIGCODEC_CLK). As the name of the clock suggests
this is supplied to the digital part of the codec. During playback it
will use this clock to transmit the audio data via the "CDC PDM" pins
to the PMIC. In this case the analog codec indirectly receives the
clock signal through the digital codec.
GCC_CODEC_DIGCODEC_CLK is already managed by the driver of the digital
part of the codec in the SoC. Having this clock on the analog PMIC part
additionally is redundant and incorrect because the analog codec cannot
receive the clock signal without going through the digital codec.

We have some KUnit tests for ASoC but they're not being run as much as
they should be since ASoC isn't enabled in the configs used by default
with KUnit and in the case of the topology tests there is no way to
enable them without enabling drivers that use them. This series
provides a Kconfig option which KUnit can use directly rather than worry
about drivers.
Further, since KUnit is typically run in UML but ALSA prevents build
with UML we need to remove that Kconfig conflict. As far as I can tell
the motiviation for this is that many ALSA drivers use iomem APIs which
are not available under UML and it's more trouble than it's worth to go
through and add per driver dependencies. In order to avoid these issues
we also provide stubs for these APIs so there are no build time issues
if a driver relies on iomem but does not depend on it. With these stubs
I am able to build all the sound drivers available in a UML defconfig
(UML allmodconfig appears to have substantial other issues in a quick
test).
With this series I am able to run the topology KUnit tests as part of a
kunit --alltests run.

a chip soft-reset, so use a regmap patch to set them to defaults.
cs35l56_reread_firmware_registers() has been removed. Its intent was to
use whatever the firmware set as a default. But the driver now patches the

The default KUnit build options are not supposed to enable any
subsystems that were not already enabled but the topology code is a
library which is generally selected by drivers that want to use it.
Since KUnit is frequently run in virtual environments with minimal
driver support this makes it difficult to enable the toplogy tests so
provide an explicit Kconfig option which can be directly enabled when
using KUnit, and also include this in the KUnit all_tests.config.

more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the wm8971 driver to use the more modern data structure.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the wm8955 driver to use the more modern data structure.
