Some typec super speed active channel switch can be controlled via
a GPIO, this binding can be used to specify the switch node by
a GPIO and the remote endpoint of its consumre.

+Typec orientation switch via a GPIO
+-----------------------------------
+
+Required properties:
+- compatible: should be set one of following:
+ - "nxp,ptn36043" for NXP Type-C SuperSpeed active switch.
+
+- gpios: the GPIO used to switch the super speed active channel,
+ GPIO_ACTIVE_HIGH: GPIO state high for cc1;
+ GPIO_ACTIVE_LOW: GPIO state low for cc1.
+- orientation-switch: must be present.
+
+Required sub-node:
+- port: specify the remote endpoint of typec switch consumer.
+
+Example:
+
+ptn36043 {
+ compatible = "nxp,ptn36043";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_ss_sel>;
+ gpios = <&gpio3 15 GPIO_ACTIVE_HIGH>;
+ orientation-switch;
+
+ port {
+ usb3_data_ss: endpoint {
+ remote-endpoint = <&typec_con_ss>;
+ };
+ };
+};
