- Add support for the OLPC XO DCON controller. This controller is
- only available on OLPC platforms. Unless you have one of these
- platforms, you will want to say 'N'.
+ 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'.
