Summary:
- Add UHD support on TM2/TM2E boards.
. adding interlace mode support and 297MHz pixel clock support
for UHD mode, setting sysreg register in case of HW trigger mode,
and adding SiI8620 MHL bridge device support.
- Fix trigger mode issue on Rinato board.
. On Rinato board, HW trigger mode doesn't work so fix it.
- Some fixup and cleanup.
* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
drm/exynos: fimd: Do not use HW trigger for exynos3250
drm/exynos/hdmi: add bridge support
drm/exynos/decon5433: signal vblank only on odd fields
drm/exynos/decon5433: add support for interlace modes
drm/exynos/hdmi: fix PLL for 27MHz settings

drm/exynos/hdmi: add 297MHz pixel clock support
drm/exynos: g2d: change platform driver name to 'exynos-drm-g2d'
drm/exynos/decon5433: configure sysreg in case of hardware trigger
Commit a6f75aa161 ("drm/exynos: fimd: add HW trigger support") added
hardware trigger support to the FIMD controller driver. I have tested
but this broke the display in at least the exynos3250 Gear 2. So until
the issue is fixed, avoid using HW trigger for the exynos3250 based
boards and use SW trigger as it was before the mentioned commit.

On TM2/TM2e platforms HDMI output is connected to MHL bridge
SiI8620. To allow configure UltraHD modes on the bridge
and to eliminate unsupported modes this bridge should be
attached to drm_encoder implemented in exynos_hdmi.

The current name is 's5p-g2d', which is identical with the driver
name of the old V4L2 driver in media/platform.
This is probably due to the DRM driver being based on the V4L2
driver when it was initially created. Still the clashing of driver
names is confusing, so rename it to something in line with the
other DRM subdrivers.

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

The size computations done in the ioctl function use an integer.
If userspace submits a request with req->cmd_nr or req->cmd_buf_nr
set to INT_MAX, the integer computations overflow later, leading
to potential (kernel) memory corruption.
Prevent this issue by enforcing a limit on the number of submitted
commands, so that we have enough headroom later for the size
computations.
Note that this change has no impact on the currently available
users in userspace, like e.g. libdrm/exynos.
While at it, also make a comment about the size computation more
detailed.

We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero. Fix this
by changing from tries-- to --tries.
A for loop would actually be the most natural way to do this. My fix
means we only loop 99 times instead of 100 but that's probably ok.

This patch replaces specific atomic commit function
with atomic helper commit one.
For this, it removes existing atomic commit function
and relevant code specific to Exynos DRM and makes
atomic helper commit to be used instead.
Below are changes for the use of atomic helper commit:
- add atomic_commit_tail callback specific to Exynos DRM
. default implemention of atomic helper doesn't mesh well
with runtime PM so the device driver which supports runtime
PM should call drm_atomic_helper_commit_modeset_enables function
prior to drm_atomic_helper_commit_planes function call.
atomic_commit_tail callback implements this call ordering.
- allow plane commit only in case that CRTC device is enabled.
. for this, it calls atomic_helper_commit_planes function
with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.

Improper usage of DECON_UPDATE register leads to subtle errors.
If it set in decon_commit when there are no active windows it results
in slow registry updates - all subsequent shadow registry updates takes more

active windows it results in garbage on the screen after suspend/resume of

First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
dma-buf kerneldoc patches
It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during

Commit aeefb36832 ("drm/exynos: gsc: add device tree support and remove
usage of static mappings") made the DRM_EXYNOS_GSC Kconfig symbol to only
be selectable if the exynos-gsc V4L2 driver isn't enabled, since both use
the same HW IP block.
But added the dependency as depends on !VIDEO_SAMSUNG_EXYNOS_GSC which is
not correct since Kconfig expressions are not boolean but tristate. So it
will only evaluate to 'n' if VIDEO_SAMSUNG_EXYNOS_GSC=y but will evaluate
to 'm' if VIDEO_SAMSUNG_EXYNOS_GSC=m.
This means that both the V4L2 and DRM drivers can be enabled if the former
is enabled as a module, which isn't what we want since otherwise 2 drivers
could attempt to use the hardware at the same time.
