PCM512x and TAS575x audio CODECs/amplifiers

These devices support both I2C and SPI (configured with pin strapping

on the board). The TAS575x devices only support I2C.

Required properties:

  - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141",

                 "ti,pcm5142", "ti,pcm5242", "ti,tas5754" or "ti,tas5756"

  - 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.  If pll-in

    and pll-out are specified in addition to a clock, the device is

    configured to accept clock input on a specified gpio pin.

  - pll-in, pll-out : gpio pins used to connect the pll using <1>

    through <6>.  The device will be configured for clock input on the

    given pll-in pin and PLL output on the given pll-out pin.  An

    external connection from the pll-out pin to the SCLK pin is assumed.

    Caution: the TAS-desvices only support gpios 1,2 and 3

Examples:

	pcm5122: pcm5122@4c {

		compatible = "ti,pcm5122";

		reg = <0x4c>;

		AVDD-supply = <&reg_3v3_analog>;

		DVDD-supply = <&reg_1v8>;

		CPVDD-supply = <&reg_3v3>;

	};

	pcm5142: pcm5142@4c {

		compatible = "ti,pcm5142";

		reg = <0x4c>;

		AVDD-supply = <&reg_3v3_analog>;

		DVDD-supply = <&reg_1v8>;

		CPVDD-supply = <&reg_3v3>;

		clocks = <&sck>;

		pll-in = <3>;

		pll-out = <6>;

	};
