[PATCH v1 00/10] qrb4210-rb2: add wsa/wcd audio playback support

[Alexey Klimov <alexey.klimov@xxxxxxxxxx>]

This is basically RFC, REVIEW or v1. At least to understand if splitting
wsa881x is a right direction and also it is not clear to me what should
be done to force mono output (to mix two channels together).

Unfortunately, only one amplifier is wired in hence only single speaker.
There is no support for capture, visense, reading wsa temperature yet.

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 wsa amplifier which can, surprisingly,
amplify the signal.

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

This series depends on:
 -- HDMI audio playback
https://lore.kernel.org/linux-sound/20241101005925.186696-1-alexey.klimov@xxxxxxxxxx/
 -- and on LPASS clock controller
https://lore.kernel.org/linux-clk/20241101012247.216825-1-alexey.klimov@xxxxxxxxxx/

The other bits like fixes for rxmacro and wcd937x codecs were accepted
as far as I understand.
