dt-bindings: gnss: add u-blox binding 



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	: GPIO connected to the "external interrupt" input pin

- 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>;

	};

};
