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. Change-Id: Ib9cf2eebdda5ce331154bc786f059c5757f34fa2 Signed-off-by: Sudheer Papothi <spapothi@codeaurora.org>
