Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:
Few cleanups to make the code more robust or readable. No functional
impact (compiled objects stay the same).
Device has up to WSA883X_MAX_SWR_PORTS number of ports and the array
assigned to prop.sink_dpn_prop has 0..WSA883X_MAX_SWR_PORTS-1 elements.
On the other hand, GENMASK(high, low) creates an inclusive mask between
<high, low>, so we need the mask from 0 up to WSA883X_MAX_SWR_PORTS-1.
Theoretically, too wide mask could cause an out of bounds read in
sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy
driver, e.g. adding incorrect number of ports via
sdw_stream_add_slave().

Two arrays (with 'struct sdw_dpn_prop' and 'struct sdw_port_config')
store configuration of Soundwire ports, thus each of their element is
indexed according to the port number (enum wsa_port_ids, e.g.
WSA883X_PORT_DAC). Except the indexing, they also store port number
offset by one in member 'num'.
Entire code depends on that correlation between array index and port
number, thus make it explicit by using designators. The code is
functionally the same, but more obvious for reading.

If reading version and variant from registers fails (which is unlikely
but possible, because it is a read over bus), the driver will proceed
and perform device configuration based on uninitialized stack variables.
Handle it a bit better - bail out without doing any init and failing the
update status Soundwire callback.

The PA gain can be set in steps of 1.5 dB from -3 dB to 18 dB, that is,
in 15 levels.
Fix the dB values for the PA volume control as experiments using wsa8835
show that the first 16 levels all map to the same lowest gain while the
last three map to the highest gain.
These values specifically need to be correct for the sound server to
provide proper volume control.
Note that level 0 (-3 dB) does not mute the PA so the mute flag should
also not be set.

In the current setup the PA is left unmuted even when the
Soundwire ports are not started streaming. This can lead to click
and pop sounds during start.
There is a same issue in the reverse order where in the PA is
left unmute even after the data stream is stopped, the time
between data stream stopping and port closing is long enough
to accumulate DC on the line resulting in Click/Pop noise
during end of stream.
making use of new mute_unmute_on_trigger flag is helping a
lot with this Click/Pop issues reported on this Codec

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 wsa883x driver to use the more modern data structure.

ASoC: Updates for v6.3
There's been quite a lot of activity this release, but not really
one big feature - lots of new devices, plus a lot of cleanup and
modernisation work spread throughout the subsystem:
- More factoring out of common operations into helper functions
by Morimoto-san.
- DT schema conversons and stylistic nits.
- Continued work on building out the new SOF IPC4 scheme.
- Support for Awinc AT88395, Infineon PEB2466, Iron Device
SMA1303, Mediatek MT8188, Realtek RT712, Renesas IDT821034,
Samsung/Tesla FSD SoC I2S, and TI TAS5720A-Q1.
Fix build errors when GPIOLIB is not set/enabled:
