+* 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];
+       };
