* Freescale Display Interface Unit

The Freescale DIU is a LCD controller, with proper hardware, it can also
drive DVI monitors.

Required properties:
- compatible : should be "fsl,diu" or "fsl,mpc5121-diu".
- reg : should contain at least address and length of the DIU register
  set.
- interrupts : one DIU interrupt should be described here.
- interrupt-parent : the phandle for the interrupt controller that
  services interrupts for this device.

Optional properties:
- edid : verbatim EDID data block describing attached display.
  Data from the detailed timing descriptor will be used to
  program the display controller.

Example (MPC8610HPCD):
	display@2c000 {
		compatible = "fsl,diu";
		reg = <0x2c000 100>;
		interrupts = <72 2>;
		interrupt-parent = <&mpic>;
	};

Example for MPC5121:
	display@2100 {
		compatible = "fsl,mpc5121-diu";
		reg = <0x2100 0x100>;
		interrupts = <64 0x8>;
		interrupt-parent = <&ipic>;
		edid = [edid-data];
	};
