WM8741 audio CODEC
This device supports both I2C and SPI (configured with pin strapping
on the board).
Required properties:
- compatible : "wlf,wm8741"
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
Example:
codec: wm8741@1a {
compatible = "wlf,wm8741";
reg = <0x1a>;
};
