Merge "driver: can: spi: add mcp25xxfd driver"

* Microchip MCP2517 stand-alone CAN controller device tree bindings

Required properties:

 - compatible: Should be one of the following:

   - "microchip,mcp2517fd" for MCP2517fd.

 - reg: SPI chip select.

 - clocks: The clock feeding the CAN controller.

 - interrupt-parent: The parent interrupt controller.

 - interrupts: Should contain IRQ line for the CAN controller.

 - gpio-controller: Marks the device node as a GPIO controller

Optional properties:

 - vdd-supply: Regulator that powers the CAN controller.

 - xceiver-supply: Regulator that powers the CAN transceiver.

 - microchip,clock_out_div = <0|1|2|4|10>: Clock output pin divider

					   0 = Start of Frame output

					   default: 10

 - microchip,clock_div2: bool: divide the internal clock by 2

 - gpio_opendrain: bool: enable open-drain for all pins (except cantx)

Example:

	can0: can@1 {

		compatible = "microchip,mcp2515";

		reg = <1>;

		clocks = <&clk24m>;

		interrupt-parent = <&gpio4>;

		interrupts = <13 0x8>;

		vdd-supply = <&reg5v0>;

		xceiver-supply = <&reg5v0>;

		gpio-controller;

	};
