This patch removes the use of dumb flags from driver.
As Dave pointed out, the dumb flags are not driver specific
so this should be removed from driver.

This patch added exynos-drm-ipp platform device registration to the exynos drm
driver. When DT is enabled, platform devices need to be registered within the
driver code. This patch fits the requirement of both DT and Non DT based drm
drivers.

This patch adds OF initialization support for the FIMC driver.
The binding documentation can be found at Documentation/devicetree/
bindings/media/samsung-fimc.txt.
The syscon regmap interface is used to serialize access to the
shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM
FIMC drivers. The DRM driver uses this interface for setting up
the FIFO data link between FIMD and FIMC IP blocks, while the V4L2
one for setting up a data link between the camera ISP and FIMC for
camera capture. The CAMBLK registers are not accessed any more
through a statically mapped IO. Synchronized access to these
registers is required for simultaneous operation of the camera
ISP and the DRM IPP on Exynos4x12.
The driver data and driver_ids static data structures are removed
since Exynos4 is going to be a dt-only platform and there is
currently no board file in mainline that defines platform data
for the FIMC IPP, i.e. uses it.
Camera input signal polarities are not currently parsed from the
device tree.

The clocks handling is refactored and a "mux" clock handling is
added to account for changes in the clocks driver. After switching
to the common clock framework the sclk_fimc clock is now split
into two clocks: a gate and a mux clock. In order to retain the
exisiting functionality two additional consumer clocks are passed
to the driver from device tree: "mux" and "parent". Then the driver
sets "parent" clock as a parent clock of the "mux" clock. These two
additional clocks are optional, and should go away when there is a
standard way of setting up parent clocks on DT platforms.

There is no need for explicit calls of devm_kfree(), as
the allocated memory will be freed during driver's detach.

Common Clock Framework introduced the need to prepare clocks before
enabling them, otherwise clk_enable() fails. This patch adds clk_prepare_enable
and clk_disable_unprepare() calls to the driver.
This patch also removes clk_disable() from fimd_remove() as it will be done
by pm_runtime_put_sync.

"Nothing overly exciting here aside from calim's fermi/kepler vram
compression patches. The rest is misc fixes I gathered from the list.
Most of the stuff from me is fixing issues that have come up from the
work on kepler PM, as well as a commit moving all the old-school
modesetting out of the way (no code changes here). There's other
patches to go on top of that, but, it'll have to wait until I can rip
out the old PM code, it's a bit tangled."

This is intended to support named (with a handle, etc) objects having
children that don't have an outside reference.
This will replace the various hacks around the place where subdev
objects have children, and have to manually drop the self-refs so
that they can be destroyed etc when all the outside refs have gone.

We need to be able to process interrupts before the DRM code is able to
actually enable them, set it up ourselves. Also, it's less convoluted
to *not* use the DRM wrappers it appears...

It'd be pretty awesome if someone would care enough to port this all
properly to a class interface, perhaps submitting a command stream to
the core via a sw object on PFIFO (emulating how EVO works basically,
and also what nvidia have done forever..)..
But, this seems unlikely given how old this hardware is now, so, lets
just hide it away.
There's a heap of other bits and pieces laying around that are still
tangled. I'll (re)move them in pieces.

Seen in the wild, don't have the hardware but this hacks things up to
treat it the same as GF119 for now.
Should be relatively safe, I'd be very surprised if anything major
changed outside of PGRAPH. PGRAPH (3D etc) is disabled by default
however until it's confirmed working.
