[PATCH 0/5] Add support for framer infrastructure and PEF2256 framer

[Herve Codina <herve.codina@xxxxxxxxxxx>]

Hi,

This series introduces the framer infrastructure and adds the PEF2256
framer provider.

Patches were previously sent as part of a full feature series and were
previously reviewed in that context:
"Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1]

In order to ease the merge, the full feature series has been split and
this series contains patches related to the framer part (infrastructure
and provider).
 - Introduce framer infrastructure (patch 1)
 - Add PEF2256 framer provider (patches 2, 3, 4, 5)

Compare to the original full feature series, a modification was done on
patch 3 in order to fix a dependency issue detected my a kernel test
robot.

Best regards,
Hervé
