SiRFstar-based GNSS Receiver DT binding SiRFstar chipsets are used in GNSS-receiver modules produced by several vendors and can use UART, SPI or I2C interfaces. Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic properties. Required properties: - compatible : Must be one of "fastrax,uc430" "linx,r4" "wi2wi,w2sg0004" "wi2wi,w2sg0008i" "wi2wi,w2sg0084i" - vcc-supply : Main voltage regulator (pin name: 3V3_IN, VCC, VDD) Required properties (I2C): - reg : I2C slave address Required properties (SPI): - reg : SPI chip select address Optional properties: - sirf,onoff-gpios : GPIO used to power on and off device (pin name: ON_OFF) - sirf,wakeup-gpios : GPIO used to determine device power state (pin name: RFPWRUP, WAKEUP) - timepulse-gpios : Time pulse GPIO (pin name: 1PPS, TM) Example: serial@1234 { compatible = "ns16550a"; gnss { compatible = "wi2wi,w2sg0084i"; vcc-supply = <&gnss_reg>; sirf,onoff-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>; sirf,wakeup-gpios = <&gpio0 17 GPIO_ACTIVE_HIGH>; }; };
