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/slave-device.txt
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>;
};
};
