+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,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>;
+ };
+};
