Yes, in a day or so. I am currently rebasing on 3.19-rc5 linux-next. I will add Tested-by from from Rahul, Javier, Inki, Sjoerd, and Gustavo. Only Inki has acked this till now. So, I will add Inki's Acked-by.

I see only a single Tested-by on this series and that seems to be with a bunch of out-of-tree patches applied on top. Does this now actually work applied on top of upstream? Also it seems like many people actually want this to get merged but there's been no Reviewed-bys and only a single Tested-by? Is that as good as it's going to get? Also I think the last update was that Ajay was going to resend this based on v3.19-rc1 or something. Is that still going to happen?

Only this version was posted 2 months ago and the first version of the series was sent on May, 2014 so it has been on the list for almost a year now...

I don't have time to review the series in details right now, but I'm happy with the DT bindings, and have no big issue with the rest of the patches. I don't really like the of_drm_find_bridge() concept introduced in 03/14 but I won't nack it given lack of time to implement an alternative proposal.

Excellent, thank you for pointing these out. I've been struggling to
get the display working on v3.18-rc and had missed these.

With the 3 patches you mention, the display is working on my peach-pi as
well.

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.

That's what I did... Linus' master branch is a moving target and if you
look at his current HEAD, it is commit fc14f9c1 ("Linux 3.18-rc5") but
as I said before, at least two patches that are needed didn't land in
Linus' tree yet. These are:
0ef76ae ("ARM: exynos_defconfig: Enable options for display panel support")
e35e305 ("drm/panel: simple: Add AUO B116XW03 panel support")
IOW, linux.git master branch + this series is not enough to have display
working AFAICT so I was wondering if I'm missing something else.
Do you have a public tree somewhere with the branch you are using to test?
Best regards,
Javier

Hi Javier,
In the cover letter, I have mentioned that it is tested on Linus tree:
"This series is based on master branch of Linus tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git"
Kindly test the patches with that.

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 145b.dp-controller: Driver exynos-dp requests probe deferral
exynos-drm exynos-drm: bound 1440.fimd (ops fimd_component_ops)
exynos-drm exynos-drm: failed to bind 145b.dp-controller (ops
exynos_dp_ops): -517
exynos-drm exynos-drm: master bind failed: -517
platform 145b.dp-controller: Driver exynos-dp requests probe deferral
Any idea what else I could be missing here?
Your patches don't apply cleanly in linux-next btw, although the are many
issues with the Exynos DRM currently in linux-next anyways so probably using
3.18-rc as a base makes more sense for now until all those things get fixed
but you should rebase so they can be picked.

Javier
