8665040850 drm/exynos: fix broken component binding in case of multiple pipelines
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.

63498e3065 drm/exynos: atomic dpms support
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()

df5225bc9a drm/exynos: consider deferred probe case
This patch makes sure that exynos drm framework handles deferred
probe case correctly.

Sub drivers could be probed before resources, clock, regulator,
phy or panel, are ready for them so we should make sure that exynos
drm core waits until all resources are ready and sub drivers are
probed correctly.

Chagelog v2:
- Make sure that exynos drm core tries to bind sub drivers only in case that
  they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:
  drm/exynos: mipi-dsi: consider panel driver-deferred probe
- Return error type correctly.

8fa04aae2a drm/exynos: hdmi: use i2c_adapter instead of i2c_client
This patch changes i2c_client for ddc to i2c_adapter
because ddc needs only i2c_adapter.

bfe4e84c6b drm/exynos: hdmi: consider APB PHY
This patch returns error in case of using APB PHY.

Exynos5420 SoC and maybe later would use APB PHY instead of
I2C PHY so such case should be considered.

af65c80487 drm/exynos: Consolidate suspend/resume in drm_drv
This patch removes all of the suspend/resume logic from the individual
drivers and consolidates it in drm_drv. This consolidation reduces the
number of functions which enable/disable the hardware to just one -- the
dpms callback. This ensures that we always power up/down in a consistent
manner.
