TCPCI stands for typec port controller interface, its implementation
has full typec port control with power delivery support, it's a
standard i2c slave with GPIO input as irq interface, detail see spec
"Universal Serial Bus Type-C Port Controller Interface Specification
Revision 1.0, Version 1.1"

+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"
+               source-pdos = <0x380190c8>;
+               sink-pdos = <0x380190c8 0x3802d0c8>;
+               op-sink-microwatt-hours = <9000000>;
+       };
