Addressed Richard's comments pertaining to error handling. Rebased. Switched to dev_err_probe() in few places (added patch #11). Fixed authorship of one of Richard's patches.] 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 the later patches, and also this way our work doesn't diverge. (I fixed missing free_irq path in cs42l42_init, did s/Soundwire/SoundWire/ in changelogs, rebased.) 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.) Patch 11 brings cs42l42-i2c.c in sync with cs42l83-i2c.c on dev_err_probe() usage.
