[PATCH v2 00/14] qrb4210-rb2: add wsa audio playback and capture support

[Alexey Klimov <alexey.klimov@xxxxxxxxxx>]

Issues with distorted sound and unstable volume on playback were resolved
and this patchset also includes support for onboard DMIC and thus
capturing feature.

This implements the playback via the following path:
RX1 from DSP is connected to rxmacro which communicates with wcd codec
using soundwire. This goes into AUX input of wcd.
wcd codec outputs analog audio into wsa8815 amplifier.
Capturing works through vamacro using one onboard DMIC which is
directly connected to vamacro codec.

Special thanks to Srini. Without his help and support this patchset
wouldn't be here.

Previous version:
https://lore.kernel.org/linux-sound/20241101053154.497550-1-alexey.klimov@xxxxxxxxxx/

Changes since v2:

-- forcing single channel output for RX_1 channel is moved into drv variant;
-- added capture feature support hence some new patches and
   updates to pins description;
-- sorted headers in wsa881x-i2c driver, removed excessive ones;
-- removed of_gpio.h as suggested by Rob;
-- removed wrong bindings and updated already existing
   qcom,wsa881x.yaml as suggested by Krzysztof;
-- removed unused pins state description as suggested by Krzysztof;
-- reworked wsa881x-i2c driver
   (initialisation, pm, consts, some functions, etc);
-- usage of devm_kmemdup() in wsa881x-i2c probe() as a hint from Krzysztof;
-- updated commit messages where required;
-- not using i2c gpio bit-banging for wsa881x i2c;
-- made dtbs_check and dt_binding_check happy.


This series depends on:
 -- HDMI audio playback
https://lore.kernel.org/linux-arm-msm/20241204140027.2198763-1-alexey.klimov@xxxxxxxxxx/
-- and LPASS clock controller
