-Allwinner sun4i low res adc attached tablet keys
-------------------------------------------------
-
-Required properties:
- - compatible: should be one of the following string:
-		"allwinner,sun4i-a10-lradc-keys"
-		"allwinner,sun8i-a83t-r-lradc"
-		"allwinner,sun50i-a64-lradc", "allwinner,sun8i-a83t-r-lradc"
- - reg: mmio address range of the chip
- - interrupts: interrupt to which the chip is connected
- - vref-supply: powersupply for the lradc reference voltage
-
-Each key is represented as a sub-node of the compatible mentioned above:
-
-Required subnode-properties:
-	- label: Descriptive name of the key.
-	- linux,code: Keycode to emit.
-	- channel: Channel this key is attached to, must be 0 or 1.
-	- voltage: Voltage in µV at lradc input when this key is pressed.
-
-Example:
-
-#include <dt-bindings/input/input.h>
-
-	lradc: lradc@1c22800 {
-		compatible = "allwinner,sun4i-a10-lradc-keys";
-		reg = <0x01c22800 0x100>;
-		interrupts = <31>;
-		vref-supply = <&reg_vcc3v0>;
-
-		button@191 {
-			label = "Volume Up";
-			linux,code = <KEY_VOLUMEUP>;
-			channel = <0>;
-			voltage = <191274>;
-		};
-
-		button@392 {
-			label = "Volume Down";
-			linux,code = <KEY_VOLUMEDOWN>;
-			channel = <0>;
-			voltage = <392644>;
-		};
-
-		button@601 {
-			label = "Menu";
-			linux,code = <KEY_MENU>;
-			channel = <0>;
-			voltage = <601151>;
-		};
-
-		button@795 {
-			label = "Enter";
-			linux,code = <KEY_ENTER>;
-			channel = <0>;
-			voltage = <795090>;
-		};
-
-		button@987 {
-			label = "Home";
-			linux,code = <KEY_HOMEPAGE>;
-			channel = <0>;
-			voltage = <987387>;
-		};
-	};
