This patch changes file license to GPL
Most of exynos files had been copied from some random
file and not updated correctly. So this patch corrects
the file license.

"this patch set updates exynos drm framework and includes minor fixups.
and this pull request except hdmi device tree support patch set posted
by Rahul Sharma because that includes media side patch so for this
patch set, we may have git pull one more time in addition, if we get
an agreement with media guys. for this patch, you can refer to below link,
http://comments.gmane.org/gmane.comp.video.dri.devel/74504
this pull request adds hdmi device tree support
and includes related patch set such as disabling of hdmi internal
interrupt, suppport for platform variants for hdmi and mixer,
support to disable video processor based on platform type and
removal of drm common platform data. as you know, this patch
set was delayed because it included an media side patch. so for this,
we got an ack from v4l2-based hdmi driver author, Tomasz Stanislawski."

when fb changing is requested, crtc's dpms mode should be on.
if not on, return -EPERM so that the hardware can't be accessed.
if user requesed dpms off and next SetCrtc with an another fb
then the hardware can be accessed with dpms off to write overlay
data onto some registers so this patch will prevent from accessing
the hardware with dpms off.

this patch fixes that when drm_crtc_helper_set_mode() is called,
mode data for hardware overlay and conntroller are updated two times.
for example, in case that drm_crtc_helper_set_mode() is called,
overlay_ops->commit() and manager_ops->commit() callbacks can be called
two times, first at drm_crtc_helper_set_mode() and second
at drm_helper_connector_dpms().

This patch adds exynos specific property for crtc mode. The crtc mode
property has tow modes - normal and blank. The normal mode is default
mode and can use crtc normally. The blank mode turns off the private
plane of crtc, so we don't see crtc screen but can see other plane
screens.

The exynos drm driver has several subdrv. They each can be module but it
causes unfixed probe order of exynodr drm driver and each subdrv. It
also needs some weird codes such as exynos_drm_fbdev_reinit and
exynos_drm_mode_group_reinit. This patch can remove weird codes and
clear codes through we doesn't modularity each subdrv.
Also this removes unnecessary codes related module.

The exynos fimd supports 5 window overlays. Only one window overlay of
fimd is used by the crtc, so we need plane feature to use the rest
window overlays.
This creates one ioctl exynos specific - DRM_EXYNOS_PLANE_SET_ZPOS, it
is the ioctl to decide for user to assign which window overlay.

this patch adds the following comments and code clean.
- add comment of exynos_drm_crtc_apply() call at page flip time.
- add comment that when exynos_drm_fbdev_reinit() is called,
why num_connector is 0 and also the framebuffers should be destroyed.
- remove buf_off member from struct exynos_drm_overlay because this member
isn't used anymore.

This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables
only FIMD yet but we will add HDMI support also in the future.
this patch is based on git repository below:
git://people.freedesktop.org/~airlied/linux.git
branch name: drm-next
commit-id: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67
you can refer to our working repository below:
http://git.infradead.org/users/kmpark/linux-2.6-samsung
branch name: samsung-drm
We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c
based on Linux framebuffer) but couldn't so because lowlevel codes
of s3c-fb.c are included internally and so FIMD module of this driver has
its own lowlevel codes.
We used GEM framework for buffer management and DMA APIs(dma_alloc_*)
for buffer allocation so we can allocate physically continuous memory
for DMA through it and also we could use CMA later if CMA is applied to
mainline.
Refer to this link for CMA(Continuous Memory Allocator):
http://lkml.org/lkml/2011/7/20/45
this driver supports only physically continuous memory(non-iommu).

v2: < http://www.spinics.net/lists/kernel/msg1224275.html >

v5: < http://comments.gmane.org/gmane.comp.video.dri.devel/60802 >
Changelog v2:
DRM: add DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl command.
this feature maps user address space to physical memory region
once user application requests DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl.
DRM: code clean and add exception codes.
Changelog v3:
DRM: Support multiple irq.
FIMD and HDMI have their own irq handler but DRM Framework can regiter
only one irq handler this patch supports mutiple irq for Samsung SoC.
DRM: Consider modularization.
each DRM, FIMD could be built as a module.
DRM: Have indenpendent crtc object.
crtc isn't specific to SoC Platform so this patch gets a crtc
to be used as common object.
created crtc could be attached to any encoder object.
DRM: code clean and add exception codes.
Changelog v4:
DRM: remove is_defult from samsung_fb.
is_default isn't used for default framebuffer.
DRM: code refactoring to fimd module.
this patch is be considered with multiple display objects and
would use its own request_irq() to register a irq handler instead of
drm framework's one.
DRM: remove find_samsung_drm_gem_object()
DRM: move kernel private data structures and definitions to driver folder.
samsung_drm.h would contain only public information for userspace
ioctl interface.
DRM: code refactoring to gem modules.
buffer module isn't dependent of gem module anymore.
DRM: fixed security issue.
DRM: remove encoder porinter from specific connector.
samsung connector doesn't need to have generic encoder.
DRM: code clean and add exception codes.
Changelog v5:
DRM: updated fimd(display controller) driver.
added various pixel formats, color key and pixel blending features.
DRM: removed end_buf_off from samsung_drm_overlay structure.
this variable isn't used and end buffer address would be
calculated by each sub driver.
DRM: use generic function for mmap_offset.
replaced samsung_drm_gem_create_mmap_offset() and
samsung_drm_free_mmap_offset() with generic ones applied
to mainline recentrly.
DRM: removed unnecessary codes and added exception codes.
DRM: added comments and code clean.
Changelog v6:
DRM: added default config options.
DRM: added padding for 64-bit align.
DRM: changed prefix 'samsung' to 'exynos'
