Merge remote-tracking branches 'asoc/topic/wm8962', 'asoc/topic/wm8974' and 'asoc/topic/wm9713' into asoc-next
WM8974 audio CODEC
This device supports both I2C and SPI (configured with pin strapping
on the board).
Required properties:
- compatible: "wlf,wm8974"
- reg: the I2C address or SPI chip select number of the device
Examples:
codec: wm8974@1a {
compatible = "wlf,wm8974";
reg = <0x1a>;
};
