This dts adds initial support for the popular ODROID U2/U3 development
boards based on Exynos4412.
This file comes from larger work by Alban Browaeys, but I removed the
items that aren't immediately working on mainline kernels yet (USB,
HDMI, etc).
This leaves us with a reasonable starting point for further development:
basic bootup and shutdown works, plus LED, eMMC, SD, and serial.

Thanks for posting, however I have already prepared dts for Odroid X2
and U3 with complete USB support. HDMI needs a few little tweaks, but I
hope it can be also merged soon.
I'm waiting for v3.16-rc1 to rebase them onto latest mainline and post
here. I will check if I can integrate your patch to them.
You can check some earlier version in the following git:

Thanks for posting, however I have already prepared dts for Odroid X2
and U3 with complete USB support. HDMI needs a few little tweaks, but I
hope it can be also merged soon.
I'm waiting for v3.16-rc1 to rebase them onto latest mainline and post
here. I will check if I can integrate your patch to them.
You can check some earlier version in the following git:

Hello Marek,
since you pointed out HDMI support on the ODROID, I assume you've looked into that. I've posted about some issues with HDMI PHY and mixer some days ago here:
http://www.spinics.net/lists/linux-samsung-soc/msg31643.html
Tomasz already suggested on IRC to CC some more people, who have worked in that area. Maybe you have an idea what is going wrong there?
With best wishes,
Tobias

Nice, thanks. I took a quick glance at your work and indeed it looks
much more complete. I don't think you have anything to add from my
patch.
Just one request, please be sure to submit this work after -rc1 comes
out even if HDMI is not working at first. Too many people have started
working on this and then stopped short of actually sending any code
upstream. If you CC me on the patches I'll try to help with reviews
too.
Thanks,
Daniel

Empirically we have managed to find that after bypassing the Video
Processor and using the Mixer alone [1], LCD0 power domain is no longer
needed for HDMI operation.
However there is still an issue with power-up and/or -down sequences
causing the whole system to hang when trying to power on and off HDMI
repeatedly. This is to be investigated yet.
[1] This can be achieved by setting .is_vp_enabled of
exynos4210_mxr_drv_data to 0, assuming that you have a patch applied
which adds appropriate compatible string to mixer_match_types[],
pointing to that struct.
Best regards,
Tomasz
