1* HiDeep Finger and Stylus touchscreen controller
2
3Required 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
8Optional 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.
