2020-06-30soundwire: bus: initialize bus clock base and scale registersPierre-Louis Bossart
The SoundWire 1.2 specification adds new registers to allow for seamless clock changes while audio transfers are on-going. Program them following the specification. Note that dynamic clock changes are not supported for now, this only adds the register initialization.
