[PATCH 0/3] ASoC: add CS42L84 codec driver

[James Calligeros <jcalligeros99@xxxxxxxxx>]

Hi all,

This patch set adds a driver for the Cirrus Logic CS42L84 codec. This chip
is (so far) found only on Apple Silicon Macs. In keeping with proud Apple
tradition, the CS42L84 is essentially just a CS42L42 with a different
regmap and no publicly available datasheet. It may also be missing its
parent's S/PDIF capabilities as none of Apple's devices support S/PDIF out,
however this cannot be positively confirmed.

This driver has lived in the downstream Asahi tree for quite a while now,
and gained some refinements along the way. I have squashed most of these
into the initial driver commit as they were small changes like tweaking
msleep()s or filling out TLVs, but left seperate a larger change to
tip/ring sense IRQ handling as it differs significantly from what is found
in the CS42L42 driver.
