We want more information about the controller type, its task, its video
pipeline position and so on.

There are no style issues, remove checkpatch.pl TODO entry.

-         Add support for the OLPC XO DCON controller.  This controller is
-         only available on OLPC platforms.   Unless you have one of these

+         In order to support very low power operation, the XO laptop uses a
+         secondary Display CONtroller, or DCON.  This secondary controller
+         is present in the video pipeline between the primary display
+         controller (integrate into the processor or chipset) and the LCD
+         panel.  It allows the main processor/display controller to be
+         completely powered off while still retaining an image on the display.
+         This controller is only available on OLPC platforms.  Unless you have
+         one of these platforms, you will want to say 'N'.

-       - checkpatch.pl cleanups
        - see if vx855 gpio API can be made similar enough to cs5535 so we can
          share more code
        - allow simultaneous XO-1 and XO-1.5 support
