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 of this specific CODEC can be moved
outside the more generic ACP code.
Changes in v3:
- Modified commit message for patch 1: ASoC: es8316: Enable support for
S32 LE format. The commit message implied that S32 LE format is the
only one that is supported by the machine driver. The AMD ACP
supports a wide variety of formats that are also supported by the
CODEC. Now the purpose of the patch is to enable one additional
format that is supported by the CODEC chip.
- Added new patch: Replace NR_SUPPORTED_MCLK_LRCK_RATIOS with ARRAY_SIZE()
No need to have a special define when we can use ARRAY_SIZE() directly.
- Reworked the MCLK div by 2 option. Now the CODEC driver will first
try to use halved frequency by checking if it can generate
suitable clocking. If it can not, then the full MCLK will be used.
In this way we can also support unknown SKU that have a too high
MCLK frequency.
- Moved generic ACP code from patch 5, that introduces the new machine
driver, to patch 4, that introduces ACP legacy callback mechanism.
- Removed the forced S32 LE format in the new machine driver.
