* Kinetis K61 CAN *

This driver implements SPI slave protocol for Freescale K61 CAN controller.

Required properties:
  - compatible: Should be "fsl,k61".
  - reg: Should contain SPI chip select.
  - interrupt-parent: Should specify interrupt controller for the interrupt.
  - interrupts: Should contain IRQ line for the CAN controller.

Optional properties:
  - reset-gpio: Reference to the GPIO connected to the reset input.
  - pinctrl-names : Names corresponding to the numbered pinctrl states.
  - pinctrl-0 : This explains the active state of the GPIO line.
  - pinctrl-1 : This explains the suspend state of the GPIO line.
  - bits-per-word: Indicate how many bits are in a SPI frame. e.g.: 8, 16, 32.
                   Default to 16.
  - reset-delay-msec: Delay in milliseconds to be applied after resetting the chip.
                      Default to 1 ms.

Example:

	can-controller@0 {
		compatible = "fsl,k61";
		reg = <0>;
		interrupt-parent = <&tlmm_pinmux>;
		interrupts = <25 0>;
		reset-gpio = <&tlmm_pinmux 11 0x1>;
		pinctrl-names = "active", "sleep";
		pinctrl-0 = <&can_rst_on>;
		pinctrl-1 = <&can_rst_off>;
		bits-per-word = <8>;
		reset-delay-msec = <100>;
	};
