3 Required properties:
4 - compatible : must be "hideep,hideep-ts"
5 - reg : I2C slave address, (e.g. 0x6C).
6 - interrupts : Interrupt to which the chip is connected.
7
8 Optional properties:
9 - vdd-supply : It is the controller supply for controlling
10 main voltage(3.3V) through the regulator.
11 - vid-supply : It is the controller supply for controlling
12 IO voltage(1.8V) through the regulator.
13 - reset-gpios : Define for reset gpio pin.
14 It is to use for reset IC.
15 - touchscreen-size-x : X axis size of touchscreen
16 - touchscreen-size-y : Y axis size of touchscreen
17 - linux,keycodes : Specifies an array of numeric keycode values to
18 be used for reporting button presses. The array can
19 contain up to 3 entries.
