+* SM SM501
+
+The SM SM501 is a LCD controller, with proper hardware, it can also
+drive DVI monitors.
+
+Required properties:
+- compatible : should be "smi,sm501".
+- reg : contain two entries:
+    - First entry: System Configuration register
+    - Second entry: IO space (Display Controller register)
+- interrupts : SMI interrupt to the cpu should be described here.
+- interrupt-parent : the phandle for the interrupt controller that
+  services interrupts for this device.
+
+Optional properties:
+- mode : select a video mode:
+    <xres>x<yres>[-<bpp>][@<refresh>]
+- edid : verbatim EDID data block describing attached display.
+  Data from the detailed timing descriptor will be used to
+  program the display controller.
+- little-endian: availiable on big endian systems, to
+  set different foreign endian.
+- big-endian: availiable on little endian systems, to
+  set different foreign endian.
+
+Example for MPC5200:
+	display@1,0 {
+		compatible = "smi,sm501";
+		reg = <1 0x00000000 0x00800000
+		       1 0x03e00000 0x00200000>;
+		interrupts = <1 1 3>;
+		mode = "640x480-32@60";
+		edid = [edid-data];
+	};
