1 Mediatek-based GNSS Receiver DT binding
2
3 Mediatek chipsets are used in GNSS-receiver modules produced by several
4 vendors and can use a UART interface.
5
6 Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
7 properties.
8
9 Required properties:
10
11 - compatible : Must be
12
13 "globaltop,pa6h"
14
15 - vcc-supply : Main voltage regulator (pin name: VCC)
16
17 Optional 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
26 Example:
27
28 serial@1234 {
29 compatible = "ns16550a";
30
31 gnss {
32 compatible = "globaltop,pa6h";
33 vcc-supply = <&vcc_3v3>;
34 };
35 };
