		WM8804 audio CODEC

		This device supports both I2C and SPI (configured with pin strapping
		on the board).

		Required properties:

		- compatible : "wlf,wm8804"

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

		Example:

		codec: wm8804@1a {
		compatible = "wlf,wm8804";
		reg = <0x1a>;
		};
