[PATCH 0/4] ASoC: amd: acp: Add sound support for a line of HUAWEI laptops

[Marian Postevca <posteuca@mutex.one>]

This series adds support for a line of HUAWEI laptops with
AMD CPUs that connect using the ACP3x module to a ES8336 codec.

The codec driver must be extended to support the S32 LE format
and the MCLK div by 2 option. MCLK div by 2 is needed for one specific
SKU which uses a 48Mhz MCLK which seems to be too high of a frequency
for the codec and must be divided by 2.

The acp legacy driver must also be extended by using callbacks so that
the more complicated handling for this specific codec can be moved
outside the more generic ACP code.

The last patch tries to avoid anoying pop sounds when the speaker/headphones
are enabled/disabled by delaying the handling of the GPIOs and using a mutex
to avoid race conditions between the speaker power event callback and the
trigger callback.

Marian Postevca (4):
  ASoC: es8316: Enable support for S32 LE format and MCLK div by 2
  ASoC: amd: acp: Add support for splitting the codec specific code from
    the ACP driver
  ASoC: amd: acp: Add machine driver that enables sound for systems with
    a ES8336 codec
  ASoC: amd: acp: Improve support for speaker power events
