| Richtek RT1718S TCPC chip |
| |
| The Richtek RT1718S chip is TCPC, but also has 3 pins, which can be used as |
| a usual GPIO. This node collects common properties 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" |
