If we are doing an MST transaction and we've gotten HPD and we
lookup the device from the incoming msg, we should take the mgr
lock around it, so that mst_primary and mstb->ports are valid.

This validates the mst_primary under the lock, and then calls
into the check and send function. This makes the code a lot
easier to understand the locking rules in.

Summary:
. Add atomic feature support
- Exynos also now supports atomic feature. However, it doesn't
guarantee atomic operation yet, and is required for more cleanups.
This time we just modified for Exynos drm driver to use atomic
interfaces instead of legacy ones. Next time, we will enhance
Exynos drm driver to support the atomic operation.
. Add iommu support
- This is a patch series according to below Exynos iommu integration
work with DT and dma-mapping subsystem,
http://lwn.net/Articles/607626/
. Consolidate Exynos drm driver initialization.
- This patch sereis resolves the issue that only the first compoments
was bound when happened deferred probing for other pipelines and
also makes the driver to be more cleanned up by moving the dispered
codes for registering kms drivers to one place.
. Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433.
- Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433
and later, which is used to transfer frame data to MIPI-DSI controller
compressing the data to reduce memory bandwidth.
- Add DECON driver for Exynos5433 SoC. This IP is a dislay controller
similar to Exynos7's one but this controller has much different registers
from Exynos7's ones so this driver has been implemented separately.
We will implement a helper modules for FIMD and two DECON controllers
to remove duplicated codes later.
- Add Exynos5433 SoC support to MIPI-DSI driver, and device tree
relevant patches.

This patch resolves the issue that refresh rate got low
at extension mode test with fimd and vidi combination.
The problem was because atomic_commit callback waited
for the completion of vblank to gaurantee crtc relevant
registers are updated from shadow registers to real ones.
However, the waiting there is really unnecessary because
page flip operation does already it.

This patch resolves page fault issue with iommu and atomic feature
when modetest test application is terminated.
ENWIN_F field of WINCONx register enables or disable a dma channel to
each hardware overlay - the value of the field will be updated to real
register after vsync.
So this patch makes sure the dma channel is disabled by waiting for vsync
one time after clearing shadow registers to all dma channels.
Below shows the page fault issue:

When the fimd is disabled by fimd_disable(), enabled overlay layers also
are disabled. If clocks for fimd are enabled by fimd_enable() on this
case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and
VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd
is disabled, so it may continue display output of prior when clocks for
fimd are enabled again.

With atomic modesetting all the control for CRTC, Planes, Encoders and
Connectors should come from DRM core, so the driver is not allowed to
enable or disable planes from inside the crtc_enable()/disable() call.
But it needs to disable planes with crtc_disable in exynos driver
internally. Because crtc is disabled before plane is disabled, it means
plane_disable just returns without any register changes, then we cannot
be sure setting register to disable plane when crtc is disable.
This patch removes this chainned calls to enable plane from exynos hw
drivers code letting only DRM core touch planes except to disable plane.
Also it leads eliminable enabled and resume of struct exynos_drm_plane.

exynos_dsi_host_transfer() can be called through a panel driver while
DSI is turning down. It is possible because the function checks only
whether DSI is initialized or not, and there is a moment which DSI is
set by uninitialized, but DSI is still turning down. To prevent it,
DSI must be set by disabled before starting to be turned down, and
exynos_dsi_host_transfer() must check whether DSI is enabled or not.

In case there are multiple pipelines and deferred probe occurs, only components
of the first pipeline were bound. As a result only one pipeline was available.
The main cause of this issue was dynamic generation of component match table -
every component driver during probe registered itself on helper list, if there
was at least one pipeline present on this list component match table were
created without deferred components.
This patch removes this helper list, instead it creates match table from
existing devices requiring exynos_drm KMS drivers. This way match table do not
depend on probe/deferral order and contains all KMS components.
As a side effect patch makes the code cleaner and significantly smaller.

The planes are already disabled by the drm_atomic_helper_commit() code
so we don't need to disable the in these two places.

Run dpms operations through the atomic intefaces. This basically removes
the .dpms() callback from econders and crtcs and use .disable() and
.enable() to turn the crtc on and off.
v2: Address comments by Joonyoung:
- make hdmi code call ->disable() instead of ->dpms()
- do not use WARN_ON on crtc enable/disable
v3: - Fix build failure after the hdmi change in v2
- Change dpms helper of ptn3460 bridge
v4: - remove win_commit() call from .enable()
v5: - move .atomic_check() to the atomic PageFlip patch, and transform it
in .atomic_begin()

exynos needs to update planes with the crtc enabled (mainly for the FIMD
case) so this specific atomic commit changes the order of
drm_atomic_helper_commit_modeset_enables() and
drm_atomic_helper_commit_planes() to commit planes after we enable crtc
and encoders.

This is a preparation commit to move exynos_drm_crtc_disable() together
with the future exynos_drm_crtc_enable() that will come from the split of
exynos_drm_crtc_dpms() callback.

Everything starts disabled so we don't really need to disable anything.

Now that no one is using the functions exported by exynos_drm_plane due
to the atomic conversion we can make remove some of the them or make them
static.
v2: remove unused exynos_drm_crtc
v3: fix checkpatch error (reported by Joonyoung)

PageFlips now use the atomic helper to work through the atomic modesetting
API. Async page flips are not supported yet.
v2: Add .atomic_begin() step to handle the vblank part we removed from
exynos page_flip code.

Now that phase 1 and 2 are complete switch .set_config helper to
