-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>;
- };
-};

+description:
+ The SiRFstar GNSS receivers have incarnated over the years in different
+ chips, starting from the SiRFstarIII which was a chip that was introduced in
+ 2004 and used in a lot of dedicated GPS devices. In 2009 SiRF was acquired
+ by CSR (Cambridge Silicon Radio) and in 2012 the CSR GPS business was
+ acquired by Samsung, while some products remained with CSR. In 2014 CSR
+ was acquired by Qualcomm who still sell some of the SiRF products.
+
+ SiRF chips can be used over UART, I2C or SPI buses.
