Support for CS42L83 on Apple machines
Merge series from Martin PoviĊĦer <povik+lin@cutebit.org>:
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.
