Hi Li Jun,
Are you working on an updated version of this patch series?
I'm pondering other changes that builds on these patches (the documentation
and the fwnode added to the tcpc_dev and tcpm primarily).
Btw, there is a semi-colon missing in your example below.

TCPCI stands for typec port controller interface, its implementation
has full typec port control with power delivery support, it's a

+TCPCI(Typec port cotroller interface) binding
+---------------------------------------------
+
+Required properties:
+- compatible: should be "usb-tcpci,chip-specific-string".
+- reg: the i2c slave address of typec port controller device.
+- interrupt-parent: the phandle to the interrupt controller which provides
+ the interrupt.
+- interrupts: interrupt specification for tcpci alert.
+
+Required sub-node:
+- connector: The "usb-c-connector" attached to the tcpci chip, the bindings
+ of connector node are specified in
+ Documentation/devicetree/bindings/connector/usb-connector.txt
+
+Example:
+
+ptn5110@50 {
+ compatible = "usb-tcpci,ptn5110";
+ reg = <0x50>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
+
+ usb_con: connector {
+ compatible = "usb-c-connector";
+ label = "USB-C";
+ port-type = "dual";
+ try-power-role = "sink"
Here!
+ source-pdos = <0x380190c8>;
+ sink-pdos = <0x380190c8 0x3802d0c8>;
+ op-sink-microwatt-hours = <9000000>;
+ };
