Texas Instruments PCM186x Universal Audio ADC



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: audio-codec@4a {

		compatible = "ti,pcm1865";

		reg = <0x4a>;



		avdd-supply = <&reg_3v3_analog>;

		dvdd-supply = <&reg_3v3>;

		iovdd-supply = <&reg_1v8>;

	};
