WM8750 and WM8987 audio CODECs
These devices support both I2C and SPI (configured with pin strapping
on the board).
Required properties:
- compatible : "wlf,wm8750" or "wlf,wm8987"
- reg : the I2C address of the device for I2C, the chip select
number for SPI.
Example:
codec: wm8750@1a {
compatible = "wlf,wm8750";
reg = <0x1a>;
};
