This series is based on master branch of Linus tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

I applied your series on top of 3.18-rc5 + linux-next's commit:

0ef76ae ("ARM: exynos_defconfig: Enable options for display panel support").

I think you should had mentioned what other patches are needed as a
dependency since I spent quite a bit of time figuring out why the
ps8622 bridge driver probe was always deferred due of_drm_find_panel()
failing and then I noticed that a patch from linux-next was needed:

e35e305 ("drm/panel: simple: Add AUO B116XW03 panel support")

With that commit the ps8622 drm bridge driver probe succeed but I still
don't have display working on an Exynos5240 Peach Pit, the kernel log shows:

platform 145b0000.dp-controller: Driver exynos-dp requests probe deferral
exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops)
exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops): -517
exynos-drm exynos-drm: master bind failed: -517
platform 145b0000.dp-controller: Driver exynos-dp requests probe deferral

do you have this in your dmesg?

...
exynos-dp-video-phy 10040728.video-phy: Failed to lookup PMU regmap
...

to get a working framebuffer out of linus 318rc4 on my peach pi, i had
to cherry pick these 3 patches:

arm: dts: Exynos5: Use pmu_system_controller phandle for dp phy
drm/exynos: dp: Remove support for unused dptx-phy
ARM: exynos_defconfig: Enable options for display panel support

Check if you have those.
