From: Andreas Dannenberg dannenberg@ti.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

+These devices support both I2C and SPI (configured with pin strapping +on the board).

+Required properties:

• • compatible : "ti,pcm1862",

•            "ti,pcm1863",
  

•            "ti,pcm1864",
  

•            "ti,pcm1865"
  

• • reg : The I2C address of the device for I2C, the chip select

•     number for SPI.
  

• • avdd-supply: Analog core power supply (3.3v)
• • dvdd-supply: Digital core power supply
• • iovdd-supply: Digital IO power supply

•    See regulator/regulator.txt for more information
  

+CODEC input pins:

• • VINL1
• • VINR1
• • VINL2
• • VINR2
• • VINL3
• • VINR3
• • VINL4
• • VINR4

+The pins can be used in referring sound node's audio-routing property.

+Example:

• pcm186x: pcm186x@4a {

audio-codec@4a

With that,
