S2500 driver supports hardware timestamping. Along with this driver, OA TC6 frame work is also changed to add hardware timestamping support. Driver has support for running selftest and loopback tests. Through ethtool, it can provide traffic stats, rmon stats, and timestamping related traffic stats. As S2500 has an internal PHY, changes have been added to onsemi's PHY driver to support this device. To: Andrew Lunn To: Piergiorgio Beruto To: Heiner Kallweit To: Russell King To: David S.

Changes in v7: - Fixed compiler warning due to prototype mismatch - Moved the order of patches to ensure dt-bindings comes first before it is being used - Added missing review tag - Added missing MODULE_DEVICE_TABLE - OA_TC6 framework enables 64 bit timestamping mode by default. - Compiler related warnings fixed. - Link to v6: https://lore.kernel.org/r/20260629-s2500-mac-phy-support-v6-0-18ce79500371@onsemi.com Changes in v6: - Changes to ensure onsemi code stay within 80 columns. - Fixed the error of "not described in comments section" in comments section. - Fixed compiler warnings. - Link to v5: https://patch.msgid.link/20260614-s2500-mac-phy-support-v5-0-89874b72f725@onsemi.com Changes in v5: - kernel doc related changes in oa_tc.c, onsemi driver files and oa tc6 rst file - Link to v4: https://lore.kernel.org/r/20260605-s2500-mac-phy-support-v4-0-de0fbc13c6d8@onsemi.com Changes in v4: - Added return value comment for genphy_read/write_phy_mmd functions - Added genphy_loopback_fixed_speed helper function to be used in set_loopback callbacks - Updated networking documentation for OA TC6 framework to elaborate on what is expected in the ptp_clock_info structure for registration. - added spi-max-frequency in YAML file based on alert from sashiko-bot - Removed model/version from the onsemi driver's private structure as they were useful as "information-only" data. - Replaced the non-standard selftest with Linux's standard selftest and made it as a separate patch - Changed bit manipulation, shift operations to use macros so that it is clean and readable. - added new read_register and write_register apis with _mms postfix so that MMS (memory map selector) can be given as a parameter. - Fixed the wrong condition check with NETIF_F_RXFCS to subtract FCS size from the length of the frame. - Link to v3: https://lore.kernel.org/r/CY8PR02MB92499C9080614FA3CEB8CD0483162@CY8PR02MB9249.namprd02.prod.outlook.com Changes in v3: - Moved OA TC6 framework to its own directory. - Split changes to smaller patches based on feedback. - Added PHY loopback support as a separate patch. - New, read and write register APIs with extra parameter MMS - Link to v2: https://lore.kernel.org/r/CY8PR02MB924920C8825C7AE5D22EFA4483382@CY8PR02MB9249.namprd02.prod.outlook.com Changes in v2: - API to add vendor specific MMS to mdio device map. - Link to v1: https://lore.kernel.org/r/CY8PR02MB9249D083B637477C254F9B0583322@CY8PR02MB9249.namprd02.prod.outlook.com --- Selvamani Rajagopal (11): dt-bindings: net: add onsemi's S2500 Documentation: networking: Add timestamp related APIs to OA TC6 framework net: ethernet: oa_tc6: Move oa_tc6.c to its own directory net: ethernet: oa_tc6: Move constant definitions to header file net: ethernet: oa_tc6: Support for hardware timestamp net: ethernet: oa_tc6: Support for vendor specific MMS net: phy: ncn26000: Support for onsemi's S2500 internal phy net: phy: ncn26000: Enable enhanced noise immunity net: phy: ncn26000: Support for loopback onsemi: s2500: Add driver support for S2500 MAC-PHY onsemi: s2500: Added selftest support to onsemi's S2500 driver .../devicetree/bindings/net/onnn,s2500.yaml | 72 +++ Documentation/networking/oa-tc6-framework.rst | 59 +++ MAINTAINERS | 13 +- drivers/net/ethernet/Kconfig | 13 +- drivers/net/ethernet/Makefile | 3 +- drivers/net/ethernet/adi/Kconfig | 1 + drivers/net/ethernet/microchip/lan865x/Kconfig | 1 + drivers/net/ethernet/oa_tc6/Kconfig | 17 + drivers/net/ethernet/oa_tc6/Makefile | 7 + drivers/net/ethernet/{ => oa_tc6}/oa_tc6.c | 433 ++++++++++++----- drivers/net/ethernet/oa_tc6/oa_tc6_ptp.c | 65 +++ drivers/net/ethernet/oa_tc6/oa_tc6_std_def.h | 161 +++++++ drivers/net/ethernet/oa_tc6/oa_tc6_tstamp.c | 224 +++++++++ drivers/net/ethernet/onsemi/Kconfig | 22 + drivers/net/ethernet/onsemi/Makefile | 7 + drivers/net/ethernet/onsemi/s2500/Kconfig | 21 + drivers/net/ethernet/onsemi/s2500/Makefile | 7 + drivers/net/ethernet/onsemi/s2500/s2500_ethtool.c | 375 +++++++++++++++ drivers/net/ethernet/onsemi/s2500/s2500_hw_def.h | 160 +++++++ drivers/net/ethernet/onsemi/s2500/s2500_main.c | 523 +++++++++++++++++++++ drivers/net/ethernet/onsemi/s2500/s2500_ptp.c | 174 +++++++ drivers/net/phy/dp83867.c | 11 +- drivers/net/phy/ncn26000.c | 63 ++- drivers/net/phy/phy_device.c | 20 + include/linux/oa_tc6.h | 25 + include/linux/phy.h | 2 + 26 files changed, 2331 insertions(+), 148 deletions(-) --- base-commit: 014d795c73837ea2339a4ea8e8f82c6e959b845d change-id: 20260601-s2500-mac-phy-support-4f3ae920fb73 Best regards, -- Selvamani Rajagopal
