+Maxim TCPCI Type-C PD controller:
+---------------------------------
+
+Required properties:
+- compatible: should be set maxim,tcpci:
+
+- reg: 0x25:the i2c slave address of typec port controller device.
+- interrupt-parent: the phandle to the interrupt controller which provides
+ the interrupt.
+- usbpd,usbpd_int: 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
