Note: I don't know anything much about video decoding on Tegra (just NV
desktop GPUs, and that was a while ago), but I had a couple small
comments on the DT binding:

I think the IRAM region needs more explanation: What is the region used
for and by what? Can it be moved, and if so does the move need to be
co-ordinated with any other piece of SW?

Let's require a clock-names property too.
