* HiDeep Finger and Stylus touchscreen controller
|
|
|
|
Required properties:
|
|
- compatible : must be "hideep,hideep-ts"
|
|
- reg : I2C slave address, (e.g. 0x6C).
|
|
- interrupts : Interrupt to which the chip is connected.
|
|
|
|
Optional properties:
|
|
- vdd-supply : It is the controller supply for controlling
|
|
main voltage(3.3V) through the regulator.
|
|
- vid-supply : It is the controller supply for controlling
|
|
IO voltage(1.8V) through the regulator.
|
|
- reset-gpios : Define for reset gpio pin.
|
|
It is to use for reset IC.
|
|
- touchscreen-size-x : X axis size of touchscreen
|
|
- touchscreen-size-y : Y axis size of touchscreen
|
|
- linux,keycodes : Specifies an array of numeric keycode values to
|
|
be used for reporting button presses. The array can
|
|
contain up to 3 entries.
|
|
|
|
Example:
|
|
|
|
#include "dt-bindings/input/input.h"
|
|
|
|
i2c@00000000 {
|
|
|
|
/* ... */
|
|
|
|
touchscreen@6c {
|
|
compatible = "hideep,hideep-ts";
|
|
reg = <0x6c>;
|
|
interrupt-parent = <&gpx1>;
|
|
interrupts = <2 IRQ_TYPE_LEVEL_LOW>;
|
|
vdd-supply = <&ldo15_reg>;
|
|
vid-supply = <&ldo18_reg>;
|
|
reset-gpios = <&gpx1 5 0>;
|
|
touchscreen-size-x = <1080>;
|
|
touchscreen-size-y = <1920>;
|
|
linux,keycodes = <KEY_HOME>, <KEY_MENU>, <KEY_BACK>;
|
|
};
