[PATCH 00/12] hantro: Enable H.264 VDPU2 (Odroid Advance Go)

[Ezequiel Garcia]

This series adds support for H.264 decoding on the PX30, RK3328
and RK3326 platforms, enabling the VDPU2 core.

Given it's tested on the Odroid Advance Go, patches 1 and 2
add the basic support to report the panel orientation to
userspace (Heiko, if you like them, feel free to pick them).
Weston (for instance) picks up the orientation automagically
and rotates the render.

Patches 3 and 4 are just low-hanging fruit that was on my backlog.

Patches 5, 6 and 7 add some helpers to avoid duplicating some processes
between Hantro G1 and VDPU2. Patches 8 and 9 enable the VDPU2 H.264.
The implementation is based on a patch from Jonas Karlman [1], which
I forwarded ported to mainline.

Finally, patches 10 to 12 add support for the VPU on Rockchip PX30 SoCs.
These patches are based on patches submitted by Paul Kocialkowski [2],
which I ported and adjusted a bit.

Tested on i.MX8MQ EVK and RK3326 Odroid Advance Go, the latter
is able to decode a 1080p sample at ~100fps nicely.

Fluster conformance testing is looking good as well, and producing
expected results:

RK3326:
  Ran 135 tests in 480.067s
  FAILED (failures=9, errors=54)

i.MX8MQ:
  Ran 135 tests in 337.491s
  FAILED (failures=9, errors=54)
