Hi Tomi,
Thank you for the feedback.
We have OMAP5 based board with no ESD & Level Translator chip.
So, I made a quick hack in tpd12s015 driver to skip using un-relevant GPIOs.
I've copied DSS DT structure from uEmv board *.dts.
However the HDMI output is not activate yet.
Here is some debug output:

I do not use uEvm BSP u-Boot. I'm forking from this source:
git://git.denx.de/u-boot-ti.git
Perhaps I'm missing some clocks initialization?
What are the correct bootargs for activating HDMI video output?
Thank you in advance for the assistance,
Dmitry

Hi Tomi,

Where can I get those unpublished omap5 and omap5-uevm display patches
to test the video out with this patch?
I'll appreciate your assistance in additional setup (like required uEvm
.dts changes and DSI panel connection short guide).
git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git

I've since added omap5 hdmi support, so omap5-uevm's hdmi output works
on that branch.
