2 ------------------------------------
5  - compatible: "adc-keys"
6  - io-channels: Phandle to an ADC channel
7  - io-channel-names = "buttons";
8  - keyup-threshold-microvolt: Voltage above or equal to which all the keys are
12 	- poll-interval: Poll interval time in milliseconds
13 	- autorepeat: Boolean, Enable auto repeat feature of Linux input
16 Each button (key) is represented as a sub-node of "adc-keys":
18 Required subnode-properties:
19 	- label: Descriptive name of the key.
20 	- linux,code: Keycode to emit.
21 	- press-threshold-microvolt: voltage above or equal to which this key is
24 No two values of press-threshold-microvolt may be the same.
25 All values of press-threshold-microvolt must be less than
26 keyup-threshold-microvolt.
