Browse Source 
WSA883x is a speaker amplifier with soundwire interface and
enumerates as soundwire slave. WSA883x supports audio playback
on speakers and has temperature sensors for better speaker
protection and enhanced boost control support. Add software
driver support to enable WSA883x speaker amplifier.
