dt-bindings: gnss: Convert UBlox Neo-6M binding to a schema 



The UBlox Neo 6M is supported by Linux thanks to its device tree
binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

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-6m"

			"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>;

	};

};
