[PATCH 00/14] media: Add V4L2 H.264 stateless encode and VC8000E support

[Paul Kocialkowski]

This series introduces support for the V4L2 H.264 stateless encode uAPI,
core and support in the hantro driver for the Verisilicon VC8000E.

While this is a first version that will likely need some level of rework,
it is already usable for most common use-cases and supports constant
bitrate rate-control.

A GStreamer tree can be used to test the series at:
https://github.com/paulkocialkowski/gstreamer/tree/v4l2codecs/h264enc
And an example pipeline would look like:
gst-launch-1.0 videotestsrc pattern=smpte num-buffers=25 ! video/x-raw,width=640,height=480 ! v4l2slh264enc rate-control=cbr bitrate=8000000 qp-min=8 qp-max=42 ! h264parse ! matroskamux ! filesink location=encode.mkv

Note that documentation for the new uAPI is intentionally left out of
this series since it has not yet received approval.
