This patch adds bindings for WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier also has a simple thermal sensor for
over temperature and speaker protection.

Bindings for the codec have been Acked by Rob, SoundWire depended patches are already applied for 5.4 and codec driver is Acked by Pierre.

Do you want me to resend these two patches separately?


thanks,
srini
