Hi, This series updates PowerQUICC QMC and TSA drivers to prepare the support for the QMC HDLC driver. Patches were previously sent as part of a full feature series: "Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1] The full feature series reached the v9 iteration. The v1 was sent the 07/25/2023 followed by the other iterations (07/26/2023, 08/09/2023, 08/18/2023, 09/12/2023, 09/22/2023, 09/28/2023, 10/11/23, 11/15/2023) and was ready to be merged in its v8. https://lore.kernel.org/linux-kernel/20231025123215.5caca7d4@xxxxxxxxxx/ The lack of feedback from the Freescale SoC and the Quicc Engine maintainers (i.e. drivers/soc/fsl/qe/ to which the QMC and TSA drivers belong) blocks the entire full feature series. These patches are fixes and improvements to TSA and QMC drivers. These drivers were previously acked by Li Yang but without any feedback from Li Yang nor Qiang Zhao the series cannot move forward. In order to ease the review/merge, the full feature series has been split and this series contains patches related to the PowerQUICC SoC part (QMC and TSA). - Perform some fixes (patches 1 to 5) - Add support for child devices (patch 6) - Add QMC dynamic timeslot support (patches 7 to 17) Compare to the previous iteration: https://lore.kernel.org/linux-kernel/20231128140818.261541-1-herve.codina@xxxxxxxxxxx/ this v2 series: - Removes a forward declaration in the driver. - Adds kernel test robot tags as the issue was detected. - Adds some missing Cc: stable. Best regards, Hervé [1]: https://lore.kernel.org/linux-kernel/20231115144007.478111-1-herve.codina@xxxxxxxxxxx/ Changes v1 -> v2: - Patch 1 Add 'Reported-by: kernel test robot <lkp@xxxxxxxxx>' Add 'Closes: https://lore.kernel.org/oe-kbuild-all/202312051959.9YdRIYbg-lkp@xxxxxxxxx/' Add 'Cc: stable@xxxxxxxxxxxxxxx' - Patch 2, 3 Add 'Cc: stable@xxxxxxxxxxxxxxx - Patch 15 Move qmc_setup_chan_trnsync() to avoid a forward declaration.
