[PATCH] ASoC: codes: Add support for ES8316 producer mode
The AMD acp-es8336 machine driver requires ES8316 run in producer mode, which is not supported previously.

This looks basically good, a few small things:

There's lots of small coding style things through this - for example here the { } isn't needed and
- lrck_divider = es8316->sysclk/params_rate(params);
- bclk_divider = lrck_divider/4;
There's a lot of cases without spaces around /.
#define ES8316_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S20_3LE | \
SNDRV_PCM_FMTBIT_S24_LE)
SNDRV_PCM_FMTBIT_S24_LE | SNDRV_PCM_FMTBIT_S32_LE)
This is adding S32_LE support which is fine but wasn't mentioned in the changelog, it should be a separate patch.

S20_3LE uses 3 bytes, is the 32 divider correct here?
