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 for lan969x (same basic features as Sparx5 provides excl. FDMA and VCAP, merged). 3) Add lan969x VCAP functionality (merged). --> 4) Add RGMII support. 5) Add FDMA support. == RGMII support: The lan969x switch device includes two RGMII port interfaces (port 28 and 29) supporting data speeds of 1 Gbps, 100 Mbps and 10 Mbps. == Patch breakdown: Patch #1 does some preparation work. Patch #2 adds new function: is_port_rgmii() to the match data ops. Patch #3 uses the is_port_rgmii() in a number of places. Patch #4 makes sure that we do not configure an RGMII device as a low-speed device, when doing a port config. Patch #5 makes sure we only return the PCS if the port mode requires it. Patch #6 adds checks for RGMII PHY modes in sparx5_verify_speeds(). Patch #7 adds registers required to configure RGMII. Patch #8 adds RGMII implementation. Patch #9 documents RGMII delays in the dt-bindings. Details are in the commit description of the individual patches v4: https://lore.kernel.org/20241213-sparx5-lan969x-switch-driver-4-v4-0-d1a72c9c4714@microchip.com v3: https://lore.kernel.org/20241118-sparx5-lan969x-switch-driver-4-v3-0-3cefee5e7e3a@microchip.com v2: https://lore.kernel.org/20241113-sparx5-lan969x-switch-driver-4-v2-0-0db98ac096d1@microchip.com v1: https://lore.kernel.org/20241106-sparx5-lan969x-switch-driver-4-v1-0-f7f7316436bd@microchip.com ==================== Link: https://patch.msgid.link/20241220-sparx5-lan969x-switch-driver-4-v5-0-fa8ba5dff732@microchip.com Signed-off-by: Jakub Kicinski --- 9268abe611b09edc975aa27e6ce829f629352ff4
