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
It uses snd_soc_component_write_field() with is the same as
regmap_write_bits(REGISTER, REGISTER_MASK,
FIELD_PREP(REGISTER_MASK, value);
So the 1 mean write in enable mask in this case, and mask is single bit,
read it exactly like if it was using FIELD_PREP(), but even for BITs.
I did check every single snd_soc_component_write_field() so far to check
it matches.
Or it's another question ?
