== Description: This series is the second of a multi-part series, that prepares and adds support for the new lan969x switch driver. The upstreaming efforts is split into multiple series (might change a bit as we go along): 1) Prepare the Sparx5 driver for lan969x (merged) --> 2) add support lan969x (same basic features as Sparx5 provides excl. FDMA and VCAP). 3) Add support for lan969x VCAP, FDMA and RGMII == Lan969x in short: The lan969x Ethernet switch family [1] provides a rich set of switching features and port configurations (up to 30 ports) from 10Mbps to 10Gbps, with support for RGMII, SGMII, QSGMII, USGMII, and USXGMII, ideal for industrial & process automation infrastructure applications, transport, grid automation, power substation automation, and ring & intra-ring topologies. The LAN969x family is hardware and software compatible and scalable supporting 46Gbps to 102Gbps switch bandwidths. == Preparing Sparx5 for lan969x: The main preparation work for lan969x has already been merged [1]. After this series is applied, lan969x will have the same functionality as Sparx5, except for VCAP and FDMA support. QoS features that requires the VCAP (e.g. PSFP, port mirroring) will obviously not work until VCAP support is added later. == Patch breakdown: Patch #1-#4 do some preparation work for lan969x Patch #5 adds new registers required by lan969x Patch #6 adds initial match data for all lan969x targets Patch #7 defines the lan969x register differences Patch #8 adds lan969x constants to match data Patch #9 adds some lan969x ops in bulk Patch #10 adds PTP function to ops Patch #11 adds lan969x_calendar.c for calculating the calendar Patch #12 makes additional use of the is_sparx5() macro to branch out in certain places. Patch #13 documents lan969x in the dt-bindings Patch #14 adds lan969x compatible string to sparx5 driver Patch #15 introduces new concept of per-target features [1] https://lore.kernel.org/netdev/20241004-b4-sparx5-lan969x-switch-driver-v2-0-d3290f581663@microchip.com/ To: David S.

(Simon) - Switched to relative includes for lan969x and sparx5. (Simon) - Ditched target verification using the DT compatible string (Krzysztof). - Fixed direct dependency warning by using 'depends on' instead of 'select' for lan969x kconfig symbol (kernel-test-robot). - Fixed issue when building as a module. Changed #ifdef CONFIG_LAN969X_SWITCH to #if IS_ENABLED(CONFIG_LAN969X_SWITCH) in mchp_sparx5_match and added EXPORT_SYMBOL_GPL to lan969x match data. - Link to v1: https://lore.kernel.org/r/20241021-sparx5-lan969x-switch-driver-2-v1-0-c8c49ef21e0f@microchip.com --- Daniel Machon (15): net: sparx5: add support for lan969x targets and core clock net: sparx5: change spx5_wr to spx5_rmw in cal update() net: sparx5: change frequency calculation for SDLB's net: sparx5: add sparx5 context pointer to a few functions net: sparx5: add registers required by lan969x net: lan969x: add match data for lan969x net: lan969x: add register diffs to match data net: lan969x: add constants to match data net: lan969x: add lan969x ops to match data net: lan969x: add PTP handler function net: lan969x: add function for calculating the DSM calendar net: sparx5: use is_sparx5() macro throughout dt-bindings: net: add compatible strings for lan969x targets net: sparx5: add compatible string for lan969x net: sparx5: add feature support .../bindings/net/microchip,sparx5-switch.yaml | 20 +- MAINTAINERS | 7 + drivers/net/ethernet/microchip/Kconfig | 1 + drivers/net/ethernet/microchip/Makefile | 1 + drivers/net/ethernet/microchip/lan969x/Kconfig | 5 + drivers/net/ethernet/microchip/lan969x/Makefile | 12 + drivers/net/ethernet/microchip/lan969x/lan969x.c | 350 +++++++++++++++++++++ drivers/net/ethernet/microchip/lan969x/lan969x.h | 57 ++++ .../ethernet/microchip/lan969x/lan969x_calendar.c | 191 +++++++++++ .../net/ethernet/microchip/lan969x/lan969x_regs.c | 222 +++++++++++++ .../ethernet/microchip/sparx5/sparx5_calendar.c | 72 +++-- .../net/ethernet/microchip/sparx5/sparx5_fdma.c | 2 +- .../net/ethernet/microchip/sparx5/sparx5_main.c | 82 ++++- .../net/ethernet/microchip/sparx5/sparx5_main.h | 75 ++++- .../ethernet/microchip/sparx5/sparx5_main_regs.h | 132 ++++++++ .../net/ethernet/microchip/sparx5/sparx5_mirror.c | 10 +- .../net/ethernet/microchip/sparx5/sparx5_netdev.c | 26 +- .../net/ethernet/microchip/sparx5/sparx5_packet.c | 16 +- .../net/ethernet/microchip/sparx5/sparx5_port.c | 46 +++ drivers/net/ethernet/microchip/sparx5/sparx5_ptp.c | 15 +- drivers/net/ethernet/microchip/sparx5/sparx5_qos.c | 3 +- .../net/ethernet/microchip/sparx5/sparx5_regs.c | 5 +- .../net/ethernet/microchip/sparx5/sparx5_regs.h | 5 +- .../net/ethernet/microchip/sparx5/sparx5_sdlb.c | 10 +- .../ethernet/microchip/sparx5/sparx5_tc_flower.c | 5 + 25 files changed, 1286 insertions(+), 84 deletions(-) --- base-commit: b0b3683419b45e2971b6d413c506cb818b268d35 change-id: 20241016-sparx5-lan969x-switch-driver-2-7cef55783938 Best regards,
