- Move bl_val and bl_dev into dcon_priv struct....
- The only time we ever read the backlight val from the dcon is
at probe time. Rather than calling dcon_get_backlight for that, just
read from the register.
- Drop dcon_get_backlight; it's just returning dcon->bl_val.
- Rename dcon_set_backlight_hw to dcon_set_backlight, and drop the
old dcon_set_backlight function. Move contents of old dcon_set_backlight
function into dconbl_set.
- Shuffle backlight_ops callbacks around to be closer to struct, and
rename them.
- Make use of new backlight_properties arg to backlight_device_register,
drop old code that set this manually.

Global variables dcon_switched, dcon_irq_time, and dcon_load_time can all be moved

This moves dcon_source and dcon_pending into the dcon_priv struct.
Because these variables are used by the IRQ handler (which is
registered in the model-specific callbacks), we end up needing
to move dcon_priv into olpc_dcon.h. This also changes the IRQ
registration to use the dcon_priv pointer as dev_id, instead of
dcon_driver.

XO-1 stuff
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.

- move fbinfo and ignore_fb_events into dcon_priv
- add calls to {un,}lock_fb_info before calling fb_blank
- fail to load the driver if there are no registered framebuffers
That last one fixes a potential oops, where if the dcon driver loads
without a framebuffer registered, fb_blank will end up being passed a
NULL (and will attempt to dereference it).

..and store it in dcon_priv. This renames it to 'monochrome',

toggled mono mode, while "echo 0 > output" enabled color.
"Echo 1 > monochrome" makes more sense to me.

The -rt patches change the console_semaphore to console_mutex. As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()
This commit makes things use more neutral function names which dont make
implications about the underlying lock.
The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()
This patch also paves the way to switching console_sem from a semaphore to
a mutex.

Drop the old geode_gpio crud, as well as the raw outl() calls; instead,
use the Linux GPIO API where possible, and the cs5535_gpio API in other
places.
Note that we don't actually clean up the driver properly yet (once loaded,
it always remains loaded). That'll come later..

Eons ago, in a galaxy far far away, Jordan committed code to work around
the fact that X might have put the DCON to sleep and then crashed (in that
galaxy, X crashed a lot; crazy, right?)
This code was based on a custom API. These days, we have code which watches
for FB unblanks, and should perform the same function.. Therefore, the older
code can be dropped. We should probably be watching for CONBLANK events to,
so allow those to turn the DCON back on.
Dropping the old code is necessary for building the driver.

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.
