WM8728 audio CODEC



This device supports both I2C and SPI (configured with pin strapping

on the board).



Required properties:



  - compatible : "wlf,wm8728"



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

          number for SPI.



Example:



codec: wm8728@1a {

	compatible = "wlf,wm8728";

	reg = <0x1a>;

};
