+* 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];
+ };
