PCM512x audio CODECs

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

Required properties:

  - compatible : One of "ti,pcm5121" or "ti,pcm5122"

  - reg : the I2C address of the device for I2C, the chip select
          number for SPI.

  - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
    device, as covered in bindings/regulator/regulator.txt

Optional properties:

  - clocks : A clock specifier for the clock connected as SCLK.  If this
    is absent the device will be configured to clock from BCLK.

Example:

	pcm5122: pcm5122@4c {
		compatible = "ti,pcm5122";
		reg = <0x4c>;

		AVDD-supply = <&reg_3v3_analog>;
		DVDD-supply = <&reg_1v8>;
		CPVDD-supply = <&reg_3v3>;
	};
