Kernel-4.18.0-80.el8_silead_gsl1680

• GSL 1680 touchscreen controller

Required properties:

• compatible : Must be one of the following, depending on the model:

            "silead,gsl1680"
            "silead,gsl1688"
            "silead,gsl3670"
            "silead,gsl3675"
            "silead,gsl3692"
  

• reg : I2C slave address of the chip (0x40)
• interrupt-parent : a phandle pointing to the interrupt controller

            serving the interrupt for this chip
  

• interrupts : interrupt specification for the gsl1680 interrupt
• power-gpios : Specification for the pin connected to the gsl1680’s

            shutdown input. This needs to be driven high to take the
            gsl1680 out of its low power state
  

• touchscreen-size-x : See touchscreen.txt
• touchscreen-size-y : See touchscreen.txt

Optional properties:

• firmware-name : File basename (string) for board specific firmware
• touchscreen-inverted-x : See touchscreen.txt
• touchscreen-inverted-y : See touchscreen.txt
• touchscreen-swapped-x-y : See touchscreen.txt
• silead,max-fingers : maximum number of fingers the touchscreen can detect
• silead,home-button : Boolean, set to true on devices which have a

            capacitive home-button build into the touchscreen
  

• vddio-supply : regulator phandle for controller VDDIO
• avdd-supply : regulator phandle for controller AVDD

Example:

i2c@00000000 {
gsl1680: touchscreen@40 {
compatible = “silead,gsl1680”;
reg = <0x40>;
interrupt-parent = <&pio>;
interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>;
power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
touchscreen-size-x = <480>;
touchscreen-size-y = <800>;
touchscreen-inverted-x;
touchscreen-swapped-x-y;
silead,max-fingers = <5>;
};
};
