[PATCH v3 00/20] ASoC: tas27{64,70}: improve support for Apple codec variants

[James Calligeros <jcalligeros99@gmail.com>]

Hi all,

This series introduces a number of changes to the drivers for
the Texas Instruments TAS2764 and TAS2770 amplifiers in order to
introduce (and improve in the case of TAS2770) support for the
variants of these amps found in Apple Silicon Macs.

Apple's variant of TAS2764 is known as SN012776, and as always with
Apple is a subtly incompatible variant with a number of quirks. It
is not publicly available. The TAS2770 variant is known as TAS5770L,
and does not require incompatible handling.

Much as with the Cirrus codec patches, I do not
expect that we will get any official acknowledgement that these parts
exist from TI, however I would be delighted to be proven wrong.

This series has been living in the downstream Asahi kernel tree[1]
for over two years, and has been tested by many thousands of users
by this point[2].
