If the s5p-cec driver is a module and the drm exynos driver is built-in, then
the CEC core will be a module also, causing the CEC notifier to fail (will be
compiled as empty functions).
To prevent this select CEC_CORE if CEC_NOTIFIER is set to ensure the CEC core
is also built into the kernel.

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

All Exynos CRTCs are fully configured by .enable callback. The only users
of mode_set_nofb actually did nothing in their callbacks - they immediately

Since possible_crtcs are set by Exynos core helper pipe fields have no
raison d'etre. The only place it was used, as a hack, is
fimd_clear_channels, to avoid calling drm_crtc_handle_vblank, but DRM core
has already other protection mechanism (vblank->enabled), so it could be
safely removed.

Convert drivers to use the new of_graph_get_remote_node() helper
instead of parsing the endpoint node and then getting the remote device
node. Now drivers can just specify the device node and which
port/endpoint and get back the connected remote device node. The details
of the graph binding are nicely abstracted into the core OF graph code.

Backmerge tag 'v4.11-rc4' into drm-next
Linux 4.11-rc4
The i915 GVT team need the rc4 code to base some more code on.
DSI forwards te-gpios interrupts to display controller, but if display
controller works in HW-TRIGGER mode this interrupt is not necessary.
Making te-gpios property optional allows to avoid generating spare
interrupts.
And also if panel device node of command mode panel device doesn't provide
te-gpios property then the panel driver failed to probe. This was a critial
issue.
With this patch we can not only get rid of 60 interrupt callbacks per second
but also fix the critial issues.

Current implementation of event handling assumes that vblank interrupt is

First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
to userspace. I also had the i915 patch in here, but that had a
small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

The drm driver .load() operation is prone to race conditions as it
initializes the driver after registering the device nodes. Its usage is
deprecated, inline it in the probe function and call drm_dev_alloc() and
drm_dev_register() explicitly.
For consistency inline the .unload() handler in the remove function as
well.

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: g2d: change platform driver name to 'exynos-drm-g2d'

The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.
As the result, exynos_drm_crtc_enable[disable]_vblank() become static
functions. They are moved around a bit to save forward declaration
though. Also while at it, we move one step further to kill
exynos_drm_crtc_from_pipe() completely by updating hdmi_bind() a bit.

Core code already makes drm_driver.get_vblank_counter hook optional by
letting drm_vblank_no_hw_counter be the default implementation for the
function hook. So the drm_vblank_no_hw_counter assignment in the driver
code becomes redundant and can be removed now.

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.

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.
