The rt*-sdw.c or max*-sdw.c devices are a better starting point for a Soundwire codec driver.
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@opensource.cirru...
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
