Seung-Woo Kim d873ab99ac drm/exynos: cleanup device pointer usages
Struct device pointer got from platform device pointer is already
alsigned as variable, but some functions do not use device pointer.
So this patch replaces thoes usages.

Sylwester Nawrocki 5186fc5e8e drm/exynos: add device tree support for fimc ipp driver
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.

Sylwester Nawrocki e5f8683923 drm/exynos: rework fimc clocks handling
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.

Sylwester Nawrocki 4c30cbc0b9 drm/exynos: remove redundant devm_kfree()
There is no need for explicit calls of devm_kfree(), as
the allocated memory will be freed during driver's detach.
Remove the redundant devm_kfree() calls from probe() and

Thierry Reding d4ed60259e drm: Convert to devm_ioremap_resource()
Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

Linus Torvalds ca5c8a4c2a Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm update from Dave Airlie:
 "Exynos and Radeon mostly, with a dma-buf and ttm fix thrown in.

  It's a bit big but its mostly exynos license fix ups and I'd rather
  not hold those up since its legally stuff.

  Radeon has a couple of fixes from dma engine work, TTM is just a
  locking fix, and dma-buf fix has been hanging around and I finally got
  a chance to review it."

Jinyoung Jeon e39d5ce132 drm/exynos: fix incorrect interrupt induced by m2m operation.
This patch fixes incorrect interrupt induced by m2m operation.
the m2m operation calls s/w reset every frame but there is the case that
the interrupt to m2m operation occures after s/w reset sometimes.
So this patch makes dma and capture operations stop at s/w reset
to avoid incorrect interrupt.

Greg Kroah-Hartman 56550d94cb Drivers: gpu: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
