es8326, es8375: controls that write each other's bits

[HyeongJun An]

Hi Zhang Yi,

I am adding a check to ASoC that warns when two controls write
overlapping bits of one register. It warns on two Everest drivers, and
I cannot tell from the driver which field is right.

es8326: ALC Capture Recovery Level and ALC Capture Target Level are both
on ES8326_ALC_LEVEL (0x33), at bits 2:0 and 3:0. The DRC Recovery Level
sits on its own ES8326_DRC_RECOVERY register. Should the ALC one be on
ES8326_ALC_RECOVERY (0x32) the same way?

es8375: DMIC Volume has shift 2 and max 4, so it writes bits 4:2 of
ES8375_ADC1 (0x17). DMIC Polarity is bit 4 of the same register. Is the
DMIC gain field only bits 3:2?

If you can confirm, I will send the fixes.

Best Regards,
HyeongJun

Hi

	Thank you very much for pointing that out.
	es8326:The ALC Capture Recovery Level should indeed be applied to bits [2:0] of reg0x32, not reg0x33.

	es8375:The ES8375_DMIC_GAIN_MAX should be 0x03

	Thank you again for your email. If possible, please let me fix these two issues this week.

Thanks and Best Regards
