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
