This adds support for V4L2 M2M based driver for E5010 JPEG Encoder
which is a stateful JPEG encoder from Imagination technologies
and is present in TI AM62A SoC.
While adding support for it, following additional framework changes were
made:
- Moved reference quantization and huffman tables provided in
ITU-T-REC-T.81 to v4l2-jpeg.c as suggested in mailing list [1].
- Add macros to round to closest integer (either higher or lower) while
rounding in order of 2.

You have a problem with your emails. Either you missed --thread when preparing
the series, or something wrong with your email setup / email servers you are
using.
