1GNSS Receiver DT binding
2
3This documents the binding structure and common properties for GNSS receiver
4devices.
5
6A GNSS receiver node is a node named "gnss" and typically resides on a serial
7bus (e.g. UART, I2C or SPI).
8
9Please 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
14Required properties:
15
16- compatible : A string reflecting the vendor and specific device the node
17 represents
18
19Optional 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
24Example:
25
26serial@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};
