Add display-timing node parsing to drm fimd and depends on the display helper patchset at http://lists.freedesktop.org/archives/dri-devel/2013-January/033998.html
It also adds pinctrl support for drm fimd.
changes since v7: - addressed comments from Joonyoung Shim jy0922.shim@samsung.com to remove a unnecessary variable.
changes since v6: addressed comments from Inki Dae inki.dae@samsung.com to separated out the pinctrl functionality and made a separate patch.
changes since v5: - addressed comments from Inki Dae inki.dae@samsung.com, to remove the allocation of 'fbmode' and replaced '-1'in "of_get_fb_videomode(dev->of_node, fbmode, -1)" with OF_USE_NATIVE_MODE.
changes since v4: - addressed comments from Paul Menzel paulepanter@users.sourceforge.net, to modify the commit message
changes since v3: - addressed comments from Sean Paul seanpaul@chromium.org, to modify the return values and print messages.
changes since v2: - moved 'devm_pinctrl_get_select_default' function call under 'if (pdev->dev.of_node)', this makes NON-DT code unchanged. (reported by: Rahul Sharma r.sh.open@gmail.com)
changes since v1: - addressed comments from Sean Paul seanpaul@chromium.org
Vikas Sajjan (2): video: drm: exynos: Add display-timing node parsing using video helper function video: drm: exynos: Add pinctrl support to fimd

Add support for parsing the display-timing node using video helper function.
The DT node parsing and pinctrl selection is done only if 'dev.of_node' exists and the NON-DT logic is still maintained under the 'else' part.

So remove or contract some log messages, e.g. "with return value" I think that is unnecessary.
