Merge "ARM: dts: msm: add mcp25xxfd support and DOC"

* 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,mcp2517fd";

		reg = <1>;

		clocks = <&clk24m>;

		interrupt-parent = <&gpio4>;

		interrupts = <13 0x8>;

		vdd-supply = <&reg5v0>;

		xceiver-supply = <&reg5v0>;

		gpio-controller;

	};

		dr_mode = "host";

	};

};

&soc {

	clk40M: can_clock {

		compatible = "fixed-clock";

		#clock-cells = <0>;

		clock-frequency = <40000000>;

	};

};

&qupv3_se0_spi {

	status = "okay";

	can@0 {

		compatible = "microchip,mcp2517fd";

		reg = <0>;

		clocks = <&clk40M>;

		interrupt-parent = <&tlmm>;

		interrupts = <15 0>;

		interrupt-names = "can_irq";

		spi-max-frequency = <10000000>;

		gpio-controller;

		status = "okay";

	};
