staging: drm/omap: call omap_gem_roll() in non-atomic ctx
If fbcon calls us from atomic context, push the work off to the
workqueue to avoid calling into the gem/dmm code in an atomic
context.

staging: drm/omap: DMM based hardware scrolling console
Add support for YWRAP scrolling by shuffling pages around in DMM
instead of sw blits.
Note that fbcon only utilizes this mode if the y resolution is
divided evenly by the font height. So, for example, a 1920x1080
display using a 16 pixel tall font will not utilize this, but a
1280x1024 display would.

staging: add omapdrm DRM/KMS driver for TI OMAP platforms
A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev)
and omap_vout (v4l2 display) drivers in the past, this driver uses the
DSS2 driver to access the display hardware, including support for
HDMI, DVI, and various types of LCD panels. And it implements GEM
support for buffer allocation (for KMS as well as offscreen buffers
used by the xf86-video-omap userspace xorg driver).
The driver maps CRTCs to overlays, encoders to overlay-managers, and
connectors to dssdev's. Note that this arrangement might change slightly
when support for drm_plane overlays is added.
For GEM support, non-scanout buffers are using the shmem backed pages
provided by GEM core (In drm_gem_object_init()). In the case of scanout
buffers, which need to be physically contiguous, those are allocated
with CMA and use drm_gem_private_object_init().
See userspace xorg driver:
git://github.com/robclark/xf86-video-omap.git
Refer to this link for CMA (Continuous Memory Allocator):

v1: http://lwn.net/Articles/458137/
v2: http://patches.linaro.org/4156/
v3: http://patches.linaro.org/4688/
v4: http://patches.linaro.org/4791/
History:
v5: move headers from include/drm at Greg KH's request, minor rebasing
on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages()
because "drm/gem: add functions to get/put pages" patch is not
merged yet
v4: bit of rework of encoder/connector _dpms() code, modeset_init()
rework to not use nested functions, update TODO.txt
v3: minor cleanups, improved error handling for dev_load(), some minor
API changes that will be needed later for tiled buffer support
v2: replace omap_vram with CMA for scanout buffer allocation, remove
unneeded functions, use dma_addr_t for physical addresses, error
handling cleanup, refactor attach/detach pages into common drm
functions, split non-userspace-facing API into omap_priv.h, remove
plugin API
v1: original
