-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)
-
-Optional properties:
-
- - wlf,fsampen:
-   FSAMPEN pin value, 0 for low, 1 for high, 2 for disconnected.
-   Defaults to 0 if left unspecified.
-
-Example:
-
-wm8782: stereo-adc {
-	compatible = "wlf,wm8782";
-	Vdda-supply = <&vdda_supply>;
-	Vdd-supply = <&vdd_supply>;
-	wlf,fsampen = <2>; /* 192KHz */
