Both mic bias and ADC's input mode depends on schematics and should be configurable. What is the better way to give access to these parameters? Device tree?
Yes.
- SOC_SINGLE("ADC Mic Bias Switch", LINEIN_CFG, MICBIAS_EN, 1, 0),
- SOC_ENUM("ADC Mic Bias Level", a1_adc_mic_bias_level),
Why would micbias be user controlled rather than a DAPM widget as normal?
Yes, I could use SND_SOC_DAPM_SUPPLY, but it supports only raw values, and doesn't supports enums. Here, I want to use enum to restrict possible values, because only these values mentioned in the documentation that I have.
A supply is an on/off switch not an enum. Users should not be selecting values at all.
