Hi all,

here is a v2 of the NVDEC support series. Changes have been done
to accommodate review comments on v1, and the NVDEC1 instance on
Tegra194 is now supported. The series has been tested on Tegra186
on top of my/Thierry's TegraDRM v8 series (though should work on
top of v7 as well).

NVDEC hardware documentation can be found at
https://github.com/NVIDIA/open-gpu-doc/tree/master/classes/video

and example userspace can be found at
https://github.com/cyndis/vaapi-tegra-driver

Thanks,
Mikko
