ADC attached resistor ladder buttons
------------------------------------
Required properties:
- compatible: "adc-keys"
- io-channels: Phandle to an ADC channel
- io-channel-names = "buttons";
- keyup-threshold-microvolt: Voltage above or equal to which all the keys are
considered up.
Optional properties:
- poll-interval: Poll interval time in milliseconds
- autorepeat: Boolean, Enable auto repeat feature of Linux input
subsystem.
Each button (key) is represented as a sub-node of "adc-keys":
Required subnode-properties:
- label: Descriptive name of the key.
- linux,code: Keycode to emit.
- press-threshold-microvolt: voltage above or equal to which this key is
considered pressed.
No two values of press-threshold-microvolt may be the same.
All values of press-threshold-microvolt must be less than
keyup-threshold-microvolt.
Example:
#include <dt-bindings/input/input.h>
adc-keys {
compatible = "adc-keys";
io-channels = <&lradc 0>;
io-channel-names = "buttons";
keyup-threshold-microvolt = <2000000>;
