Wolfson Arizona class audio SoCs

These devices are audio SoCs with extensive digital capabilites and a range

of analogue I/O.

Required properties:

  - compatible : one of the following chip-specific strings:

	"wlf,wm5102"

	"wlf,wm5110"

  - reg : I2C slave address when connected using I2C, chip select number when

    using SPI.

  - interrupts : The interrupt line the /IRQ signal for the device is

    connected to.

  - interrupt-controller : Arizona class devices contain interrupt controllers

    and may provide interrupt services to other devices.

  - interrupt-parent : The parent interrupt controller.

  - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.

    The first cell is the IRQ number.

    The second cell is the flags, encoded as the trigger masks from

    Documentation/devicetree/bindings/interrupts.txt

  - gpio-controller : Indicates this device is a GPIO controller.

  - #gpio-cells : Must be 2. The first cell is the pin number and the

    second cell is used to specify optional parameters (currently unused).

  - AVDD1-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply, CPVDD-supply,

    SPKVDDL-supply, SPKVDDR-supply : power supplies for the device, as covered

    in Documentation/devicetree/bindings/regulator/regulator.txt

Optional properties:

  - wlf,reset : GPIO specifier for the GPIO controlling /RESET

  - wlf,ldoena : GPIO specifier for the GPIO controlling LDOENA

  - wlf,gpio-defaults : A list of GPIO configuration register values. If

    absent, no configuration of these registers is performed. If any

    entry has a value that is out of range for a 16 bit register then

    the chip default will be used.  If present exactly five values must

    be specified.

Example:

codec: wm5102@1a {

	compatible = "wlf,wm5102";

	reg = <0x1a>;

	interrupts = <347>;

	#interrupt-cells = <2>;

        interrupt-parent = <&gic>;

	gpio-controller;

	#gpio-cells = <2>;

	wlf,gpio-defaults = <

		0x00000000, /* AIF1TXLRCLK */

		0xffffffff,

		0xffffffff,

		0xffffffff,

		0xffffffff,

	>;

};

Analog Devices ADAU1701

Required properties:

 - compatible:		Should contain "adi,adau1701"

 - reg:			The i2c address. Value depends on the state of ADDR0

			and ADDR1, as wired in hardware.

Optional properties:

 - reset-gpio: 		A GPIO spec to define which pin is connected to the

			chip's !RESET pin. If specified, the driver will

			assert a hardware reset at probe time.

Examples:

	i2c_bus {

		adau1701@34 {

			compatible = "adi,adau1701";

			reg = <0x34>;

			reset-gpio = <&gpio 23 0>;

		};

	};
