The Richtek RT1715 is a Type-C Port Controller (TCPC) chip.
|
|
|
|
Example:
|
|
|
|
ports {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
port0: usbc-port@0 {

reg = <0>;
|
|
tcpc = <&rt1715_tcpc0>;
|
|
vbus = <&vbus0>;
|
|
power-role = "sink";
|
|
sink-pdos = <PDO_FIXED(5000, 100, 0)>;
|
|
};
|
|
};
|
|
|
|
vbus0: vbus {
|
|
compatible = "zephyr,usb-c-vbus-adc";
|
|
status = "okay";
|
|
io-channels = <&adc 2>;
|
|
output-ohms = <10000>;
|
|
full-ohms = <(100000 + 10000)>;
|
|
};
|
|
|
|
i2c1 {
|
|
status = "okay";
|
|
clock-frequency = <I2C_BITRATE_FAST_PLUS>;
|

GPIO pin for VCONN control. RT1715 does not have built-in VCONN power supply. If the
|
|
state of the VCONN power supply need to be toggled, this pin and a switchable power
|
|
supply are required.

|
|
|
vconn-disc-gpios:

GPIO pin for VCONN discharge control. RT1715 does not have VCONN discharge capability.
|
|
If VCONN discharge is not needed, this pin does not need to be defined in the device
|
|
tree. Otherwise, this pin and a discharge path are required.
