Subject: [PATCH 2/2] ASoC: codecs: es8311: add everest es8311 codec support
Add support for the Everest-semi ES8311 codec.
Everest-semi ES8311 codec is a low-power mono audio codec with I2S audio
interface and I2C control.
Supported features:
* Both master and slave mode. Master clock is optional in slave mode.
* Sample rates from 8KHz to 96KHz.
* Sample formats: S16_LE, S18_3LE, S20_3LE, S24_3LE, S24_LE and S32_LE.
* I2S formats: I2S, LEFT_J, DSP_A, DSP_B.
* BCLK and FSYNC clocks inversion.
* Component suspend/resume.
* ADC, PGA, DAC controls.
* ADC DSP controls: volume, fade (ramp rate), ALC, automute, HPF, EQ.
* DAC DSP controls: volume, fade (ramp rate), DRC, EQ.
* DAPM routes: capture path with input source selection (differential
MIC/DMIC) and AIF channel source selection; playback path with DAC
channel source selection.
Limitations:
* Support only for master clocks with a ratio of ADC (or DAC) clock to
LRCLK equal to 256. This to keep the default ADC and DAC oversampling
and ADC scale settings. Anyway all 8-96KHz sample rates are supported
when the ratio of MCLK to sample rate is 32, 64, 128, 256, 384 or 512
(upper limit due to max MCLK freq of 49.2MHz).
* Coefficients for ADC HPF and ADC/DAC EQ not supported.
* Digital mic supported but not tested.
* S18_3LE, S20_3LE and S24_3LE formats supported but not tested.
