-Elantech I2C Touchpad
-
-Required properties:
-- compatible: must be "elan,ekth3000".
-- reg: I2C address of the chip.
-- interrupts: interrupt to which the chip is connected (see interrupt
- binding[0]).
-
-Optional properties:
-- wakeup-source: touchpad can be used as a wakeup source.
-- pinctrl-names: should be "default" (see pinctrl binding [1]).
-- pinctrl-0: a phandle pointing to the pin settings for the device (see
- pinctrl binding [1]).
-- vcc-supply: a phandle for the regulator supplying 3.3V power.
-- elan,trackpoint: touchpad can support a trackpoint (boolean)
-- elan,clickpad: touchpad is a clickpad (the entire surface is a button)
-- elan,middle-button: touchpad has a physical middle button
-- elan,x_traces: number of antennas on the x axis
-- elan,y_traces: number of antennas on the y axis
-- some generic touchscreen properties [2]:
- * touchscreen-size-x
- * touchscreen-size-y
- * touchscreen-x-mm
- * touchscreen-y-mm
