1* SM SM501
2
3The SM SM501 is a LCD controller, with proper hardware, it can also
4drive DVI monitors.
5
6Required properties:
7- compatible : should be "smi,sm501".
8- reg : contain two entries:
9    - First entry: System Configuration register
10    - Second entry: IO space (Display Controller register)
11- interrupts : SMI interrupt to the cpu should be described here.
12
13Optional properties:
14- mode : select a video mode:
15    <xres>x<yres>[-<bpp>][@<refresh>]
16- edid : verbatim EDID data block describing attached display.
17  Data from the detailed timing descriptor will be used to
18  program the display controller.
19- little-endian: available on big endian systems, to
20  set different foreign endian.
21- big-endian: available on little endian systems, to
22  set different foreign endian.

24Example for MPC5200:
25	display@1,0 {
26		compatible = "smi,sm501";
27		reg = <1 0x00000000 0x00800000
28		       1 0x03e00000 0x00200000>;
29		interrupts = <1 1 3>;
30		mode = "640x480-32@60";
31		edid = [edid-data];
32	};
