  1. * SM SM501
  2.  
  3. The SM SM501 is a LCD controller, with proper hardware, it can also
  4. drive DVI monitors.
  5.  
  6. Required 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. - interrupt-parent : the phandle for the interrupt controller that
  13.   services interrupts for this device.
  14.  
  15. Optional properties:
  16. - mode : select a video mode:
  17.     <xres>x<yres>[-<bpp>][@<refresh>]
  18. - edid : verbatim EDID data block describing attached display.
  19.   Data from the detailed timing descriptor will be used to
  20.   program the display controller.
  21. - little-endian: available on big endian systems, to
  22.   set different foreign endian.
  23. - big-endian: available on little endian systems, to
  24.   set different foreign endian.
  25.  
  26. Example for MPC5200:
  27.       [email protected],0 {
  28.             compatible = "smi,sm501";
  29.             reg = <1 0x00000000 0x00800000
  30.                    1 0x03e00000 0x00200000>;
  31.             interrupts = <1 1 3>;
  32.             mode = "[email protected]";
  33.             edid = [edid-data];
