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
Excellent, thank you for pointing these out. I've been struggling to get the display working on v3.18-rc and had missed these.
ARM: exynos_defconfig: Enable options for display panel support
Check if you have those.
With the 3 patches you mention, the display is working on my peach-pi as well.
Thanks,
Kevin
