| * 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>; |
| }; |
| }; |
