staging: olpc_dcon: mark driver as broken The commit eecb3e4e5d9d ("staging: olpc_dcon: add OLPC display controller (DCON) support") added this driver in 2010, and has been in staging since then. It was marked as broken at some point because it didn't even build but that got removed once the build issues were addressed. But it seems that the work to move this driver out of staging has stalled, the last non-trivial change to fix one of the items mentioned in its todo file was commit e40219d5e4b2 ("staging: olpc_dcon: allow simultaneous XO-1 and XO-1.5 support") in 2019. And even if work to destage the driver is resumed, the fbdev subsystem has been deprecated for a long time and instead it should be ported to DRM. Now this driver is preventing to land a kernel wide change, that makes the num_registered_fb symbol to be private to the fbmem.c file. So let's just mark the driver as broken. Someone can then work on making it not depend on the num_registered_fb symbol, allowing to drop the broken dependency again.

staging: olpc_dcon: allow simultaneous XO-1 and XO-1.5 support This patch remove model related configuration. Since the module can decide which platform data to use itself base on current running olpc board. Also change module dependency from (GPIO_CS5535 || GPIO_CS5535=n) to (GPIO_CS5535 || ACPI) because original one does not make any sense and module only doing real work when GPIO_CS5535 or ACPI is setted.

So revert it, adding back the driver, so people's machines still work properly.

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>

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.
