This node collects common proprties for RT1718S chip e.g. I2C address. Feature-specific(GPIO, TCPC) properties should be placed in a child node e.g. a number of GPIOs. Example: &i2c2_0 { rt1718s_port0: rt1718s@40 { compatible = "richtek,rt1718s"; reg = <0x40>; irq-gpios = <&gpioe 1 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>; rt1718s_gpio_port0: rt1718s_gpio { compatible = "richtek,rt1718s-gpio-port"; gpio-controller; #gpio-cells = <2>; ngpios = <3>; }; }; }; compatible: "richtek,rt1718s" include: [i2c-device.yaml] properties: irq-gpios: type: phandle-array description: Interrupt GPIO pin connected from the chip(IRQB)
