GNSS Receiver DT binding
|
||
|
|
|
||
|
|
This documents the binding structure and common properties for GNSS receiver
|
||
|
|
devices.
|
||
|
|
|
||
|
|
A GNSS receiver node is a node named "gnss" and typically resides on a serial
|
||
|
|
bus (e.g. UART, I2C or SPI).
|
||
|
|
|
||
|
|
Please refer to the following documents for generic properties:
|
||
|
|
|
||
|
|
Documentation/devicetree/bindings/serial/serial.yaml
|
||
|
|
Documentation/devicetree/bindings/spi/spi-bus.txt
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : A string reflecting the vendor and specific device the node
|
||
|
|
represents
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- lna-supply : Separate supply for an LNA
|
||
|
|
- enable-gpios : GPIO used to enable the device
|
||
|
|
- timepulse-gpios : Time pulse GPIO
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
serial@1234 {
|
||
|
|
compatible = "ns16550a";
|
||
|
|
|
||
|
|
gnss {
|
||
|
|
compatible = "u-blox,neo-8";
|
||
|
|
|
||
|
|
vcc-supply = <&gnss_reg>;
|
||
|
|
timepulse-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;
|
||
|
|
|
||
|
|
current-speed = <4800>;
|
||
|
|
};
|
||
|
|
};
