Flexcan CAN controller on Freescale's ARM and PowerPC system-on-a-chip (SOC).

Required properties:

- compatible : Should be "fsl,<processor>-flexcan"

  An implementation should also claim any of the following compatibles
  that it is fully backwards compatible with:

  - fsl,p1010-flexcan

- reg : Offset and length of the register set for this device
- interrupts : Interrupt tuple for this device

Optional properties:

- clock-frequency : The oscillator frequency driving the flexcan device

- xceiver-supply: Regulator that powers the CAN transceiver

- big-endian: This means the registers of FlexCAN controller are big endian.
              This is optional property.i.e. if this property is not present in
              device tree node then controller is assumed to be little endian.
              if this property is present then controller is assumed to be big
              endian.

Example:

	can@1c000 {
		compatible = "fsl,p1010-flexcan";
		reg = <0x1c000 0x1000>;
		interrupts = <48 0x2>;
		interrupt-parent = <&mpic>;
		clock-frequency = <200000000>; // filled in by bootloader
	};
