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}; 38
