+GlobalTop GNSS Receiver DT binding
+
+The GlobalTop GNSS receivers uses UART interfaces.
+
+Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
+properties.
+
+Required properties:
+
+- compatible	: Must be
+
+			"globaltop,pa6h"
+
+- vcc-supply	: Main voltage regulator
+
+Optional properties:
+
+- timepulse-gpios	: Time pulse GPIO
+- v-bckp-supply	: Backup voltage regulator
+
+Example:
+
+&uart_A {
+	status = "okay";
+	pinctrl-0 = <&uart_a_pins>;
+	pinctrl-names = "default";
+
+	gnss {
+		compatible = "globaltop,pa6h";
+		vcc-supply = <&vcc_3v3>;
+		current-speed = <9600>;
+	};
+};
