staging: olpc_dcon: add OLPC display controller (DCON) support
This adds DCON support for the OLPC XO. The DCON is found in XO-1 and
XO-1.5 hardware. The XO-1 has a CS5536 southbridge, while the XO-1.5
has a Via chipset; the GPIO magic that's necessary to communicate with
the DCON chip is unfortunately different across both platforms. This
driver supports both.
This driver is in bad state atm, so I'm requesting its inclusion into
staging so it can be cleaned up while staying in the kernel tree.
Original driver by Dave Woodhouse, and modified extensively by
Jordan Crouse, myself, Deepak Saxena, Paul Fox, Daniel Drake, and
probably others that I've missed.
