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.
