* 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";

	};
