To properly support a line of Huawei laptops with AMD CPU and a ES8336 codec connected to the ACP3X module we need to enable the S32 LE format and the codec option to divide the MCLK by 2.
The 32 bit support and MCLK division are two separate changes so should be two separate patches.
- lrck_divider = es8316->sysclk / params_rate(params);
- mclk_div_option = device_property_read_bool(component->dev,
"everest,mclk-div-by-2");
- if (mclk_div_option) {
This introduces a DT property but there's no documentation for it, but I don't see why we'd want this in the bindings - the driver should be able to tell from the input clock rate and required output/internal clocks if it needs to divide MCLK.
