-
-    The Freescale DIU is a LCD controller, with proper hardware, it can also
-    drive DVI monitors.
-
-    Required properties:
-    - compatible : should be "fsl-diu".
-    - reg : should contain at least address and length of the DIU register
-      set.
-    - Interrupts : one DIU interrupt should be describe here.
-
-    Example (MPC8610HPCD)
-	display@2c000 {
-		compatible = "fsl,diu";

-    - reg : should contain the address and the lenght of the FPPGA register
