+Mediatek-based GNSS Receiver DT binding
+
+Mediatek chipsets are used in GNSS-receiver modules produced by several
+vendors and can use a UART interface.
+
+Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
+properties.
+
+Required properties:
+
+- compatible : Must be
+
+ "globaltop,pa6h"
+
+- vcc-supply : Main voltage regulator (pin name: VCC)
+
+Optional properties:
+
+- current-speed : Default UART baud rate
+- gnss-fix-gpios : GPIO used to determine device position fix state
+ (pin name: FIX, 3D_FIX)
+- reset-gpios : GPIO used to reset the device (pin name: RESET, NRESET)
+- timepulse-gpios : Time pulse GPIO (pin name: PPS1, 1PPS)
+- vbackup-supply : Backup voltage regulator (pin name: VBAT, VBACKUP)
+
+Example:
+
+serial@1234 {
+ compatible = "ns16550a";
+
+ gnss {
+ compatible = "globaltop,pa6h";
+ vcc-supply = <&vcc_3v3>;
+ };
+};
