+* PTN5150 CC (Configuration Channel) Logic device
+
+PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
+connector application with CC control logic detection and indication functions.
+It is interfaced to the host controller using an I2C interface.
+
+Required properties:
+- compatible: should be "nxp,ptn5150"
+- reg: specifies the I2C slave address of the device
+- int-gpio: should contain a phandle and GPIO specifier for the GPIO pin
+ connected to the PTN5150's INTB pin.
+- vbus-gpio: should contain a phandle and GPIO specifier for the GPIO pin which
+ is used to control VBUS.
+- pinctrl-names : a pinctrl state named "default" must be defined.
+- pinctrl-0 : phandle referencing pin configuration of interrupt and vbus
+ control.
+
+Example:
+ ptn5150@1d {
+ compatible = "nxp,ptn5150";
+ reg = <0x1d>;
+ int-gpio = <&msmgpio 78 GPIO_ACTIVE_HIGH>;
+ vbus-gpio = <&msmgpio 148 GPIO_ACTIVE_HIGH>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&ptn5150_default>;
+ status = "okay";
+ };
