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. This patch series is based on the Christian Eggers PTP support for KSZ9563. Applied the Christian patch and updated as per the latest refactoring of KSZ series code. The features added on top are PTP packet Interrupt implementation based on nested handler, LAN937x two step timestamping and programmable per_out pins. Link: https://www.spinics.net/lists/netdev/msg705531.html Patch v1 -> v2 - GPIO perout enable bit is different for LAN937x and KSZ9x. Added new patch for configuring LAN937x programmable pins. - PTP enabled in hardware based on both tx and rx timestamping of all the user ports. - Replaced setting of 802.1AS bit with P2P bit in PTP_MSG_CONF1 register. RFC v2 -> Patch v1 - Changed the patch author based on past patch submission - Changed the commit message prefix as net: dsa: microchip: ptp Individual patch changes are listed in correspondig commits. RFC v1 -> v2 - Added the p2p1step timestamping and conditional execution of 2 step for LAN937x only. - Added the periodic output support Arun Ramadoss (5): net: dsa: microchip: ptp: add 4 bytes in tail tag when ptp enabled net: dsa: microchip: ptp: enable interrupt for timestamping net: dsa: microchip: ptp: add support for perout programmable pins net: dsa: microchip: ptp: lan937x: add 2 step timestamping net: dsa: microchip: ptp: lan937x: Enable periodic output in LED pins Christian Eggers (8): net: dsa: microchip: ptp: add the posix clock support net: dsa: microchip: ptp: Initial hardware time stamping support net: dsa: microchip: ptp: manipulating absolute time using ptp hw clock net: ptp: add helper for one-step P2P clocks net: dsa: microchip: ptp: add packet reception timestamping net: dsa: microchip: ptp: add packet transmission timestamping net: dsa: microchip: ptp: move pdelay_rsp correction field to tail tag net: dsa: microchip: ptp: add periodic output signal MAINTAINERS | 1 + drivers/net/dsa/microchip/Kconfig | 11 + drivers/net/dsa/microchip/Makefile | 5 + drivers/net/dsa/microchip/ksz_common.c | 45 +- drivers/net/dsa/microchip/ksz_common.h | 48 + drivers/net/dsa/microchip/ksz_ptp.c | 1157 +++++++++++++++++++++++ drivers/net/dsa/microchip/ksz_ptp.h | 88 ++ drivers/net/dsa/microchip/ksz_ptp_reg.h | 142 +++ include/linux/dsa/ksz_common.h | 54 ++ include/linux/ptp_classify.h | 71 ++ net/dsa/tag_ksz.c | 271 +++++- 11 files changed, 1875 insertions(+), 18 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 base-commit: c9f8d73645b6f76c8d14f49bc860f7143d001cb7
