GNSS Receiver DT binding

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/slave-device.txt
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
+
- enable-gpios : GPIO used to enable the device
21
+
- timepulse-gpios : Time pulse GPIO
22
+
23
+
Example:
24
+
25
+
serial@1234 {
26
+
compatible = "ns16550a";
27
+
28
+
gnss {
29
+
compatible = "u-blox,neo-8";
30
+
31
+
vcc-supply = <&gnss_reg>;
32
+
timepulse-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
33
+
34
+
current-speed = <4800>;
35
+
};
36

};
