[PATCH v2 0/6] Add support for QMC HDLC

[Herve Codina <herve.codina@bootlin.com>]

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 and
needed parts were merged in v6.8-rc1:
 - "Prepare the PowerQUICC QMC and TSA for the HDLC QMC driver" [2]
 - "Add support for framer infrastructure and PEF2256 framer" [3]

This series contains patches related to the QMC HDLC part (QMC HDLC
driver):
 - Introduce the QMC HDLC driver (patches 1 and 2)
 - Add timeslots change support in QMC HDLC (patch 3)
 - Add framer support as a framer consumer in QMC HDLC (patch 4)

Compare to the original full feature series, a modification was done on
patch 3 in order to use a coherent prefix in the commit title.

I kept the patches unsquashed as they were previously sent and reviewed.
Of course, I can squash them if needed.

Compared to the previous iteration:
  https://lore.kernel.org/lkml/20240123164912.249540-1-herve.codina@bootlin.com/
this v2 series:
- Update the qmc_hdlc initialisation in qmc_hcld_recv_complete()
- Use WARN_ONCE()
- Add a new bitmap function and use bitmap_*() in the QMC HDLC driver.

Best regards,
Hervé
