Merge branch 'net-lan969x-add-rgmii-support'Daniel Machon says:====================net: lan969x: add RGMII support== Description:This series is the fourth of a multi-part series, that prepares and addssupport for the new lan969x switch driver.The upstreaming efforts is split into multiple series (might change abit 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 28and 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 patchesv4: https://lore.kernel.org/20241213-sparx5-lan969x-switch-driver-4-v4-0-d1a72c9c4714@microchip.comv3: https://lore.kernel.org/20241118-sparx5-lan969x-switch-driver-4-v3-0-3cefee5e7e3a@microchip.comv2: https://lore.kernel.org/20241113-sparx5-lan969x-switch-driver-4-v2-0-0db98ac096d1@microchip.comv1: 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.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>
