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/linux-kernel/20240222142219.441767-1-herve.cod...@bootlin.com/ this v5 series mainly: - Update some piece of code to improve readability. - Release resources before printing error messages. - Use 'struct device *dev' and dev_err_probe() in probe(). - Use guard() and scoped_guard() from cleanup.h for spinlock locking. Best regards, Hervé [1]: https://lore.kernel.org/linux-kernel/20231115144007.478111-1-herve.cod...@bootlin.com/ [2]: https://lore.kernel.org/linux-kernel/20231205152116.122512-1-herve.cod...@bootlin.com/ [3]: https://lore.kernel.org/linux-kernel/20231128132534.258459-1-herve.cod...@bootlin.com/ Changes v4 -> v5 - Patch 1 Update QMC_HDLC_RX_ERROR_FLAGS to improve readability. Display an error message after releasing resources instead of before. Use 'struct device *dev' in probe(). Use dev_err_probe() in probe(). Do not print a message on -ENOMEM. Use guard() and scoped_guard(). - Patch 3 Use '(). See' constructing in kernel-doc instead of '() (See ...' Add 'Co-developed-by: Herve Codina <herve.cod...@bootlin.com>' - Patch 4 Use 'struct device *dev' in probe(). Use dev_err_probe() in probe(). Use '%64pb' instead of '%*pb' in printk formats. - Patch 5 Use 'struct device *dev' in probe(). Use guard() Changes v3 -> v4 - Patch 1 Remove of.h and of_platform.h includes, add mod_devicetable.h. Add a blank line in the includes list. - Path 2 No changes. - v3 patches 3 and 4 removed - Patch 3 (new patch in v4) Introduce bitmap_{scatter,gather}() based on the original patch done by Andy Shevchenko. Address comments already done on the original patch: https://lore.kernel.org/lkml/20230926052007.3917389-3-andriy.shevche...@linux.intel.com/ - Removed the returned values. - Used 'unsigned int' for all indexes. - Added a 'visual' description of the operations in kernel-doc. - Described the relationship between bitmap_scatter() and bitmap_gather(). - Moved bitmap_{scatter,gather}() to the bitmap.h file. - Improved bitmap_{scatter,gather}() test. - Reworked the commit log. - Patch 4 (v3 patch 5) Use bitmap_{scatter,gather}() - Patches 5 (v3 patch 6) No changes. 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 Andy Shevchenko (1): lib/bitmap: Introduce bitmap_scatter() and bitmap_gather() helpers Herve Codina (4): net: wan: Add support for QMC HDLC MAINTAINERS: Add the Freescale QMC HDLC driver entry 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 | 787 +++++++++++++++++++++++++++++++++ include/linux/bitmap.h | 101 +++++ lib/test_bitmap.c | 42 ++ 6 files changed, 950 insertions(+) create mode 100644 drivers/net/wan/fsl_qmc_hdlc.c -- 2.43.0
