If there are no further comments, I'm going to merge this patchset in
time for today's PR of drm-misc-next-fixes.

Hi,
This series introduces the QMC HDLC support.
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
The QMC HDLC driver provides support for HDLC using the QMC (QUICC
Multichannel Controller) to transfer the HDLC data.

DCP (Data Co-Processor) is able to derive private keys for a fused
random seed, which can be referenced by handle but not accessed by
the CPU. Similarly, DCP is able to store arbitrary keys in four

These keys can be used to perf
Enabling trusted keys requires at least one trust source implementation

DCP (Data Co-Processor) is the little brother of NXP's CAAM IP.
