| 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>; |
| }; |
| }; |
