[PATCH v1 00/11] Tegra DC improvements

[Svyatoslav Ryhel]

Greetings Tom!

I was thinking about what you asked about ACKs/Tested-By/Reviewed-By's.

Before these patches, DC and video support was available only for T20,
so the main concern is regressions towards T20. Thierry has no T20
boards at all which is rather unfortunate.

I have made a list of T20 boards which use driver I have patched:
- seaboard
- harmony
- ventana (we tested this patches on TF101 which is almost  full ventana copy)
- paz00
- colibri_t20
- tec
- medcom-wide

Maybe someone from the paz00 community will agree to help. Patches are
made in a way that no changes into existing setups are needed.

Patchset additionally includes 2 changes to the simple-panel driver.
It was written by Simon Glass, so maybe Simon would like to take a
look at changes.

P. S. Unfortunately I can not show the full potential of these patches
right now, they will shine only once I will submit T30 devices
support, which rely on video out as the main output source.
