    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 };
