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:

v2: http://patches.linaro.org/4156/

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

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

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().
