    1 GNSS Receiver DT binding
    2 
    3 This documents the binding structure and common properties for GNSS receiver
    4 devices.
    5 
    6 A GNSS receiver node is a node named "gnss" and typically resides on a serial
    7 bus (e.g. UART, I2C or SPI).
    8 
    9 Please refer to the following documents for generic properties:
   10 
   11         Documentation/devicetree/bindings/serial/serial.yaml
   12         Documentation/devicetree/bindings/spi/spi-bus.txt
   13 
   14 Required properties:
   15 
   16 - compatible    : A string reflecting the vendor and specific device the node
   17                   represents
   18 
   19 Optional properties:
   20 - lna-supply    : Separate supply for an LNA
   21 - enable-gpios  : GPIO used to enable the device
   22 - timepulse-gpios       : Time pulse GPIO
   23 
   24 Example:
   25 
   26 serial@1234 {
   27         compatible = "ns16550a";
   28 
   29         gnss {
   30                 compatible = "u-blox,neo-8";
   31 
   32                 vcc-supply = <&gnss_reg>;
   33                 timepulse-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
   34 
   35                 current-speed = <4800>;
   36         };
   37 };
