WM8782 stereo ADC
This device does not have any control interface or reset pins.
Required properties:
- compatible : "wlf,wm8782"
- Vdda-supply : phandle to a regulator for the analog power supply (2.7V - 5.5V)
- Vdd-supply : phandle to a regulator for the digital power supply (2.7V - 3.6V)
Example:
wm8782: stereo-adc {
compatible = "wlf,wm8782";
Vdda-supply = <&vdda_supply>;
Vdd-supply = <&vdd_supply>;
};
