Subject: [PATCH 0/8] Additional features for Hantro HEVC

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.

All these patches enhance the HEVC support for Hantro (G2) hardware.
Unluckily they almost all touch the same pieces of code, where buffer
size, offset and addresses are set, so they have to be in this order.
They depend of the series pushed in this pull request:
https://www.spinics.net/lists/linux-media/msg193744.html
