Hi all, there's a CS42L83 headphone jack codec found in Apple computers (in the recent 'Apple Silicon' ones as well as in earlier models, one example [1]). The part isn't publicly documented, but it appears almost identical to CS42L42, for which we have a driver in kernel. This series adapts the CS42L42 driver to the new part, and makes one change in anticipation of a machine driver for the Apple computers. Patch 1 adds new compatible to the cs42l42 schema. Patches 2 to 7 are taken from Richard's recent series [2] adding soundwire support to cs42l42. They are useful refactorings to build on in later patches, and also this way our work doesn't diverge. I made one fix: I added a call of common_remove at the end of i2c_probe should the cs42l42_init call fail (both before and after the split to cs42l42-i2c.c). Also s/Soundwire/SoundWire/ in the changelogs. Patch 8 exports some regmap-related symbols from cs42l42.c so they can be used to create cs42l83 regmap in cs42l83-i2c.c later. Patch 9 is the cs42l83 support proper. Patch 10 implements 'set_bclk_ratio' on the cs42l42 core. This will be called by the upcoming ASoC machine driver for 'Apple Silicon' Macs. (We have touched on this change to be made in earlier discussion, see [3] and replies.)
