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/linux-kernel/20240130084035.115086-1-herve.codina@bootlin.com/ this v3 series: - Remove 'inline' function specifier from .c file. - Fixed a bug introduced in the previous iteration. - Remove one lock/unlock sequence in the QMC HDCL xmit path. - Use bitmap_from_u64(). Best regards, Hervé [1]: https://lore.kernel.org/linux-kernel/20231115144007.478111-1-herve.codina@bootlin.com/ [2]: https://lore.kernel.org/linux-kernel/20231205152116.122512-1-herve.codina@bootlin.com/ [3]: https://lore.kernel.org/linux-kernel/20231128132534.258459-1-herve.codina@bootlin.com/ Changes v2 -> v3 - Patch 1 Remove 'inline' function specifier from .c file. Fix a bug introduced when added WARN_ONCE(). The warn condition must be desc->skb (descriptor used) instead of !desc->skb. Remove a lock/unlock section locking the entire qmc_hdlc_xmit() function. - Patch 5 Use bitmap_from_u64() everywhere instead of bitmap_from_arr32() and bitmap_from_arr64(). Changes v1 -> v2 - Patch 1 Use the same qmc_hdlc initialisation in qmc_hcld_recv_complete() than the one present in qmc_hcld_xmit_complete(). Use WARN_ONCE() - Patch 3 (new patch in v2) Make bitmap_onto() available to users - Patch 4 (new patch in v2) Introduce bitmap_off() - Patch 5 (patch 3 in v1) Use bitmap_*() functions - Patch 6 (patch 4 in v1) No changes Changes compare to the full feature series: - Patch 3 Use 'net: wan: fsl_qmc_hdlc:' as commit title prefix Patches extracted: - Patch 1 : full feature series patch 7 - Patch 2 : full feature series patch 8 - Patch 3 : full feature series patch 20 - Patch 4 : full feature series patch 27 Herve Codina (6): net: wan: Add support for QMC HDLC MAINTAINERS: Add the Freescale QMC HDLC driver entry bitmap: Make bitmap_onto() available to users bitmap: Introduce bitmap_off() net: wan: fsl_qmc_hdlc: Add runtime timeslots changes support net: wan: fsl_qmc_hdlc: Add framer support MAINTAINERS | 7 + drivers/net/wan/Kconfig | 12 + drivers/net/wan/Makefile | 1 + drivers/net/wan/fsl_qmc_hdlc.c | 807 +++++++++++++++++++++++++++++++++ include/linux/bitmap.h | 3 + lib/bitmap.c | 45 +- 6 files changed, 874 insertions(+), 1 deletion(-) create mode 100644 drivers/net/wan/fsl_qmc_hdlc.c -- 2.43.0
