Subject: [PATCH v3 2/2] ASoC: codecs: Add initial PCM1862/63/64/65 universal ADC driver
From: Andreas Dannenberg <dannenberg@...com>
This is an initial version of the PCM186x codec driver supporting both
2-channel and 4-channel device variants. Not all device features are
supported yet such as master/slave mode PLL configuration for which the
codec driver currently relies on the PCM186x built-in clock
auto-detection feature or the connection of digital microphones.
However here is what's here and what should work:
- Support for SPI and I2C low-level interfaces
- Regmap support and basic register definitions
- Input Mixer and Mux selection
- I2C, LJ, and TDM DAI format support

Changes from v2:
- Moved PM to set_bias_level
Changes from v1:
- Remove extra debug statements
- Fix volume control names
- Power up supplies before device reset
