Kernel-4.18.0-80.el8_sis_i2c

  • SiS I2C Multiple Touch Controller

Required properties:

  • compatible: must be “sis,9200-ts”
  • reg: i2c slave address
  • interrupt-parent: the phandle for the interrupt controller
    (see interrupt binding 0)
  • interrupts: touch controller interrupt (see interrupt
    binding 0)

Optional properties:

  • pinctrl-names: should be “default” (see pinctrl binding 1).
  • pinctrl-0: a phandle pointing to the pin settings for the
    device (see pinctrl binding 1).
  • attn-gpios: the gpio pin used as attention line
  • reset-gpios: the gpio pin used to reset the controller
  • wakeup-source: touchscreen can be used as a wakeup source

Example:

sis9255@5c  {
    compatible = "sis,9200-ts";
    reg = <0x5c>;
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_sis>;
    interrupt-parent = <&gpio3>;
    interrupts = <19 IRQ_TYPE_EDGE_FALLING>;
    irq-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
    reset-gpios = <&gpio2 30 GPIO_ACTIVE_LOW>;
};
