+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,
+ >;
+};
