The LAN937x switch has capable for supporting IEEE 1588 PTP protocol. This patch series add PTP support and tested using the ptp4l application. LAN937x has the same PTP register set similar to KSZ9563, hence the implementation has been made common for the ksz switches. KSZ9563 does not support two step timestamping but LAN937x supports both. Tested the 1step & 2step p2p timestamping in LAN937x and p2p1step timestamping in KSZ9563. RFC v1 -> v2 - Added the p2p1step timestamping and conditional execution of 2 step for LAN937x only. - Added the periodic output support Arun Ramadoss (7): net: dsa: microchip: adding the posix clock support net: dsa: microchip: Initial hardware time stamping support net: dsa: microchip: Manipulating absolute time using ptp hw clock net: dsa: microchip: enable the ptp interrupt for timestamping net: dsa: microchip: Adding the ptp packet reception logic net: dsa: microchip: add the transmission tstamp logic net: dsa: microchip: ptp: add periodic output signal Christian Eggers (1): net: ptp: add helper for one-step P2P clocks drivers/net/dsa/microchip/Kconfig | 12 + drivers/net/dsa/microchip/Makefile | 5 + drivers/net/dsa/microchip/ksz_common.c | 44 +- drivers/net/dsa/microchip/ksz_common.h | 48 + drivers/net/dsa/microchip/ksz_ptp.c | 1117 +++++++++++++++++++++++ drivers/net/dsa/microchip/ksz_ptp.h | 96 ++ drivers/net/dsa/microchip/ksz_ptp_reg.h | 136 +++ include/linux/dsa/ksz_common.h | 55 ++ include/linux/ptp_classify.h | 73 ++ net/dsa/tag_ksz.c | 288 +++++- 10 files changed, 1859 insertions(+), 15 deletions(-) create mode 100644 drivers/net/dsa/microchip/ksz_ptp.c create mode 100644 drivers/net/dsa/microchip/ksz_ptp.h create mode 100644 drivers/net/dsa/microchip/ksz_ptp_reg.h create mode 100644 include/linux/dsa/ksz_common.h

A process-related pattern I noticed in your patches. The Author: is in general the same as the first Signed-off-by:. I don't know of cases where that's not true. There can be more subsequent Signed-off-by: tags, and those are people through the hands of whom those patches have passed, and who might have made changes to them. When you use Christian's patches (verbatim or with non-radical rework, like fixes here and there, styling rework, commit message rewrite), you need Christian to appear in the Author: and first Signed-off-by: field, and you in the second. When patches are more or less a complete rework (such that it no longer resembles Christian's original intentions and it would be misleading to put his sign off on something which he did not write), you can put yourself as author and first sign off, and use Co-developed-by: + Signed-off-by for Christian's work (the sign off still seems to be required for some reason). You need to use your judgement here, you can't always put your name on others' work. You can also say "based on a previous patch posted on the mailing lists which was heavily reworked" and provide a Link: tag with a lore.kernel.org or patchwork.kernel.org link. Under the "---" sign in the patch you can also clarify the changes you've made, if you decide to keep Christian's authorship but make significant but not radical changes. These annotations will always be visible in patchwork even if not in git. At least that's what I would do.
