1Mediatek-based GNSS Receiver DT binding
2
3Mediatek chipsets are used in GNSS-receiver modules produced by several
4vendors and can use a UART interface.

6Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
7properties.

9Required properties:
10
11- compatible	: Must be
12
13			"globaltop,pa6h"
14
15- vcc-supply	: Main voltage regulator (pin name: VCC)
16
17Optional properties:
18
19- current-speed		: Default UART baud rate
20- gnss-fix-gpios	: GPIO used to determine device position fix state
21			  (pin name: FIX, 3D_FIX)
22- reset-gpios		: GPIO used to reset the device (pin name: RESET, NRESET)
23- timepulse-gpios	: Time pulse GPIO (pin name: PPS1, 1PPS)
24- vbackup-supply	: Backup voltage regulator (pin name: VBAT, VBACKUP)
25
26Example:
27
28serial@1234 {
29	compatible = "ns16550a";
30
31	gnss {
32		compatible = "globaltop,pa6h";
33		vcc-supply = <&vcc_3v3>;
34	};
