Kernel-4.18.0-80.el8_hideep

• HiDeep Finger and Stylus touchscreen controller

Required properties:

• compatible : must be “hideep,hideep-ts”
• reg : I2C slave address, (e.g. 0x6C).
• interrupt-parent : Interrupt controller to which the chip is connected.
• 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>;
};
