-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 ┬ÁV at lradc input when this key is pressed.
