2016-04-04Revert "Staging: olpc_dcon: Remove obsolete driver"Greg Kroah-Hartman1-0/+35
This reverts commit 82ef33af9dd30075adbd9f3dd161b606b8ba88ac. It turns out these machines are still out there, and the original patch broke them. So revert it, adding back the driver, so people's machines still work properly.

2013-10-15staging/olpc_dcon: fix kconfig to fix build errorsRandy Dunlap1-1/+2
Fix build errors when GPIO_CS5535=m and FB_OLPC_DCON=y by preventing that kconfig combination.

2011-02-18staging: olpc_dcon: drop CONFIG_BROKEN dependencyAndres Salomon1-1/+1

2011-02-18staging: olpc_dcon: add config options for XO_1 and XO_1_5, drop hardcoded XO-1 stuffAndres Salomon1-0/+20
This adds CONFIG_FB_OLPC_DCON_1 and CONFIG_FB_OLPC_DCON_1_5 options for allowing selection of XO-1 and/or XO-1.5 DCON support. In the process, it also forces the xo_1.c and xo_1_5.c files to build as separate units, correctly selects between XO-1 and XO-1.5 at runtime, and adds some hacks to allow xo_1_5.c to build. This isn't the cleanest patch, but it'll get better as more global variables are dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-10-05Staging: olpc_dcon: mark the driver as CONFIG_BROKEN for nowGreg Kroah-Hartman1-1/+1

2010-09-29staging: olpc_dcon: add OLPC display controller (DCON) supportAndres Salomon1-0/+8
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.
