[PATCH 0/9] media: rkvdec: Add HEVC backend

[Jonas Karlman]

This series add a HEVC backend to the Rockchip Video Decoder driver.

A version of this HEVC backend has been in use by the LibreELEC distro
for the past 3+ years [1]. It was initially created based on a copy of
the H264 backend, unstable HEVC uAPI controls and a cabac table + scaling
matrix functions shamelessly copied 1:1 from the Rockchip mpp library.

It has since then been extended to use the stable HEVC uAPI controls and
improved opon e.g. to include support for rk3288 and fix decoding issues
by Alex Bee and Nicolas Dufresne.

The version submitted in this series is based on the code currently used
by the LibreELEC distro, excluding hard/soft reset, and with cabac table
and scaling matrix functions picked from Sebastian Fricke prior series
to add a HEVC backend [2].

Big thanks to Alex Bee, Nicolas Dufresne and Sebastian Fricke for making
this series possible!

Patch 1 add the new HEVC backend.
Patch 2-3 add variants support to the driver.
Patch 4 add support for a rk3288 variant.
Patch 5 add a rk3328 variant to work around hw quirks.
Patch 6-7 add device tree node for rk3288.
Patch 8-9 extend vdec node reg size to include cache/perf registers.

This was tested on a ROCK Pi 4 (RK3399) and Rock64 (RK3328):

  v4l2-compliance 1.24.1, 64 bits, 64-bit time_t
  ...
  Total for rkvdec device /dev/video1: 46, Succeeded: 46, Failed: 0, Warnings: 0

  Running test suite JCT-VC-HEVC_V1 with decoder FFmpeg-H.265-V4L2-request
  ...
  Ran 135/147 tests successfully

  Running test suite JCT-VC-MV-HEVC with decoder FFmpeg-H.265-V4L2-request

And on a TinkerBoard (RK3288):

  v4l2-compliance 1.24.1, 32 bits, 32-bit time_t
  ...
  Total for rkvdec device /dev/video3: 47, Succeeded: 47, Failed: 0, Warnings: 0

  Running test suite JCT-VC-HEVC_V1 with decoder FFmpeg-H.265-V4L2-request
  ...
  Ran 137/147 tests successfully

  Running test suite JCT-VC-MV-HEVC with decoder FFmpeg-H.265-V4L2-request
  ...
  Ran 9/9 tests successfully

This series depend on the following series:
- media: rkvdec: Add H.264 High 10 and 4:2:2 profile support [3]

To fully runtime test this series you need above series and ffmpeg
patches from [4], this series and its depends is also available at [5].

Full summary of fluster run can be found at [6].
