Basic HEVC support has been added to Hantro driver in this pull request:
https://www.spinics.net/lists/linux-media/msg193744.html

Thanks to that it is now possible to support more features for this driver.

The first patch allow to log the hardware performance per macroblock.
The second patch makes the driver use compressed reference frames to
reduce memory bandwidth consumption.
Patches 3 to 5 allow to decode and produce 10-bits P010 frames.
Patch 6 make usage of G2 post processor to scale down the frames.
Patches 7 and 8 add the support of HEVC scaling matrix by adding a new
control.

For the next cover letter, please make sure you provide
some notes about how this was tested, with a gstreamer
public branch if needed; and also fluendo's fluster conformance
results before/after this patchset.

While there, make sure you check for performance regressions/improvements
and add such information to the commit descriptions. The more the merrier.

Thanks a lot,
Ezequiel
