Add the new hdmi phandle to exynos4.dtsi. This phandle is needed by the
s5p-cec driver to initialize the CEC notifier framework.

Tested with my Odroid U3.

Mauro, you should not apply it. It is already going through samsung-soc [1].
if you need this patch for bisectability or any other reasons, I
provided a tag with it here:
https://www.spinics.net/lists/devicetree/msg171182.html

Please drop the patch because now it will get duplicated.

Best regards,
Krzysztof

I apologize for that. I realized that I shouldn't have included this in
my pull request when it was already merged.

My fault completely.

Having exactly the same patch applied on multiple trees usually is
not a problem, provided that it doesn't rise a non-trivial
conflict.

I avoid rebase the tree where this patch is applied, as rebasing it
affect the workflow of other developers.

I'm afraid that, if I revert this patch, it will cause more harm than
good. 

So, I guess the best solution to fix the issue would be to pull from 
a stable branch on your tree with has this patch and solve conflicts,
if any. This way, nothing will popup when merging upstream.

Mauro

Of course, revert is wrong. The patch should be dropped with rebase,
assuming that you accept the rebase itself. But if you do not
rebase... then it has to  stay.

This is why I provided it in separate tag, in first place!
That is a proper solution for avoiding any patch duplication and
conflicts. Indeed you are right that duplication of commits should not
do any harm... but it is not a proper way of development, right?

Anyway, it is up to you. I provided you a tag with it so you can merge
it if needed (which would require rebasing). If not, then of course
please do not revert it.

Best regards,
Krzysztof
