One could also have a look at the patch chain I am working on for cs42l43: https://lore.kernel.org/all/20230804104602.395892-1-ckeepax@xxxxxxxxxxxxxxxxxxxxx/ It is an MFD device which is a little more complex (and I wouldn't recommend unless you really need it) but the basic SoundWire code provides a pretty clean example, the chip doesn't have too many oddities compared to cs35l56. Thanks, Charles
