MIXER on Exynos5 SoCs uses different synchronisation method than Exynos4
to update internal state (shadow registers).
Apparently the driver implements it incorrectly. The rule should be
as follows:
- do not request updating registers until previous request was finished,
ie. MXR_CFG_LAYER_UPDATE_COUNT must be 0.
- before setting registers synchronisation on VSYNC should be turned off,
ie. MXR_STATUS_SYNC_ENABLE should be reset,
- after finishing MXR_STATUS_SYNC_ENABLE should be set again.
The patch hopefully implements it correctly.

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

This reverts commit 0586feba32
This patch makes it to need get_vblank_counter callback in crtc
to get frame counter from decon driver.
However, drm_dev->max_vblank_count is a member unique to
vendor's DRM driver but in case of ARM DRM, some CRTC devices
don't provide the frame counter value. As a result, this patch
made extension and clone mode not working.
Instead of this patch, we may need separated max_vblank_count
which belongs to each CRTC device, or need to implement frame
counter emulation for them who don't support HW frame counter.

The current implementation assumes that the only possible peripheral
device for DSIM is a panel. Using an output bridge child device
should also be possible.
If an output bridge is available, don't create a new connector.
Instead, call drm_bridge_attach() and set encoder's bridge to NULL
in order to avoid an out bridge from being visible by the framework, as
the DSI bus needs control on enabling its child output bridge.
Such sequence is required by Toshiba TC358764 bridge, which is a DSI
peripheral bridge device.

Add calls to pm_runtime_force_{suspend,resume} as SYSTEM_SLEEP_PM_OPS for
all drivers for the real Exynos DRM hardware modules. This ensures that
the resources will be released for the system PM suspend/resume cycle.

In the current code, exynos_drm_suspend() function is called after all
real devices (CRTCs, Encoders, etc) are suspended, because Exynos DRM
virtual platform device is created as last device in the system (as
a part of DRM registration). None of the devices for real hardware
modules has its own system suspend/resume callbacks, so it doesn't
change any order of the executed code, but it has a side-effect:
runtime PM callbacks for real devices are not executed, because those
devices are considered by PM core as already suspended. This might
cause issues on boards with complex pipelines, where something
depends on the runtime PM state of the given device.
To ensure that exynos_drm_suspend() is called before any suspend
callback from the real devices, assign it to .prepare callback. Same
for exynos_drm_resume(), using .complete callback ensures that all
real devices have been resumed when calling it.

. it replaces several reference/unreference functions with Linux
kernel nameing standard.
Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.
Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".
Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

- Two cleanups
. One is to just remove mode_set callback from MIPI-DSI driver
because drm_display_mode data is already available from crtc
atomic state.
. And other is to just use new return type, vm_fault_t
for page fault handler.

The callback was used only to copy provided mode to context for later
usage. Since the mode is always available from crtc atomic state this code
can be removed.

Exynos Scaler is a hardware module, which processes graphic data fetched
from memory and transfers the resultant dato another memory buffer.
Graphics data can be up/down-scaled, rotated, flipped and converted color
space. Scaler hardware modules are a part of Exynos5420 and newer Exynos
SoCs.

This patch adapts Exynos DRM FIMC driver to new IPP v2 core API.
The side effect of this conversion is a switch to driver component API
to register properly in the Exynos DRM core.

This patch adapts Exynos DRM GScaler driver to new IPP v2 core API.
The side effect of this conversion is a switch to driver component API
to register properly in the Exynos DRM core. During the conversion
driver has been adapted to support more specific compatible strings
to distinguish between Exynos5250 and Exynos5420 (different hardware
limits). Support for Exynos5433 variant has been added too
(different limits table, removed dependency on ARCH_EXYNOS5).

This patch adds Exynos IPP v2 subsystem and userspace API.
New userspace API is focused ONLY on memory-to-memory image processing.
The two remainging operation modes of obsolete IPP v1 API (framebuffer
writeback and local-path output with image processing) can be implemented
using standard DRM features: writeback connectors and additional DRM planes
with scaling features.
V2 IPP userspace API is based on stateless approach, which much better fits
to memory-to-memory image processing model. It also provides support for
all image formats, which are both already defined in DRM API and supported
by the existing IPP hardware modules.
The API consists of the following ioctls:
- DRM_IOCTL_EXYNOS_IPP_GET_RESOURCES: to enumerate all available image
processing modules,
- DRM_IOCTL_EXYNOS_IPP_GET_CAPS: to query capabilities and supported image
formats of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_GET_LIMITS: to query hardware limitiations for
selected image format of given IPP module,
- DRM_IOCTL_EXYNOS_IPP_COMMIT: to perform operation described by the
provided structures (source and destination buffers, operation rectangle,
transformation, etc).
The proposed userspace API is extensible. In the future more advanced image
processing operations can be defined to support for example blending.
Userspace API is fully functional also on DRM render nodes, so it is not
limited to the root/privileged client.
Internal driver API also has been completely rewritten. New IPP core
performs all possible input validation, checks and object life-time
control. The drivers can focus only on writing configuration to hardware
registers. Stateless nature of DRM_IOCTL_EXYNOS_IPP_COMMIT ioctl simplifies
the driver API. Minimal driver needs to provide a single callback for
starting processing and an array with supported image formats.
