All of these values are BIT()s or 2-4 ORed BIT()s, can you check what they mean?
Same for almost all other snd_soc_component_ write/modify functions

the immediate break makes it look like you're just looking for the first set bit, 1-indexed, and there's functions for that
Indeed, let's use that

This comment is very confusing
It is, not sure if I can clarify it more

similarly to the swr port map, this should be commonized for WCDxxxx
Yes, but where ?
