|
|
|
|
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 */
|
|
};
