Bindings define interface between driver and DTS. The values are
abstract, so alwys start from 0 or 1 and are incremented by 1, not by
power of 2. Also missing some sort of prefix, w.g. WCD9390_xxx

Anyway, this does not look like binding.


Ack,

Will add the Prefix WCD9370_SWRM_CH1,


Added new binding support header file (include/dt-bindings/sound/qcom,wcd93xx.h) for providing channel mapping values to avoid having
to use unclear number indices in device trees.

Best regards,
Krzysztof
