[PATCH v2 4/8] dt-bindings: gnss: add u-blox binding

Johan Hovold
2018-05-30T10:34:30Z

Add binding for u-blox GNSS receivers.

Note that the u-blox product names encodes form factor (e.g. "neo"),
chipset (e.g. "8") and variant (e.g. "q"), but that only formfactor and
chipset is used for the compatible strings (for now).

+u-blox GNSS Receiver DT binding
+
+The u-blox GNSS receivers can use UART, DDC (I2C), SPI and USB interfaces.
+
+Please see Documentation/devicetree/bindings/gnss/gnss.txt for generic
+properties.
+
+Required properties:
+
+- compatible : Must be one of
+
+ "u-blox,neo-8"
+ "u-blox,neo-m8"
+
+- vcc-supply : Main voltage regulator
+
+Required properties (DDC):
+- reg : DDC (I2C) slave address
+
+Required properties (SPI):
+- reg : SPI chip select address
+
+Required properties (USB):
+- reg : Number of the USB hub port or the USB host-controller port
+ to which this device is attached
+
+Optional properties:
+
+- timepulse-gpios : Time pulse GPIO
+- u-blox,extint-gpios : External interrupt GPIO
+- v-bckp-supply : Backup voltage regulator
+
+Example:
+
+serial@1234 {
+ compatible = "ns16550a";
+
+ gnss {
+ compatible = "u-blox,neo-8";
+
+ v-bckp-supply = <&gnss_v_bckp_reg>;
+ vcc-supply = <&gnss_vcc_reg>;
+ };
+};
