Thanks you very much!

Yes, I got yours point about wrapping panel into the bridge. But I don't
think that it's worth the effort right now because each Tegra output has
it's own implantation of the connector and it should be cleaner not to
touch that code.

Secondly, I don't have hardware to test all available panel output types
on Tegra and the benefits of messing with all that code are a bit dim to me.

I can make a patch to wrap the RGB panel into a bridge, but this should
make code a bit inconsistent in regards to not having a common code path
for the "legacy" nvidia,panel. So perhaps it's better to leave it all
as-is for now.
