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

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.

- Add IPP v2 framework.
. it is a rewritten version of the Exynos mem-to-mem image processing
framework which supprts color space conversion, image up/down-scaling
and rotation. This new version replaces existing userspace API with
new easy-to-use and simple ones so we have already applied the use of
these API to real user, Tizen Platform[1], and also makes existing
Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API.
And below are patch lists we have applied to a real user,

TDM(Tizen Display Manager) is a Display HAL for Tizen platform.
Ps. Only real user using IPP API is Tizen.

- 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.
