It introduces new compatible strings to distinguish between MAC0/1 and MAC2/3, as their delay chains and configuration units differ. The device tree bindings are updated to restrict the allowed phy-mode and delay properties for each MAC type. Corresponding changes are made to the device tree source files and the FTGMAC100 driver to support the new delay configuration. This enables precise RGMII timing configuration for AST2600-based platforms, improving interoperability with various PHYs Signed-off-by: Jacky Chou --- Changes in v5: - Remove the new property, "aspeed,rgmii-delay-ps" from yaml and driver - Add aspeed,scu to aspeed-g6 dtsi back - Determine delay value from bootloader and tx/rx-internal-delay-ps to configure RGMII delay value with phy-mode - Add a helper for AST2600 to get phy driver handle - Link to v4: https://lore.kernel.org/r/20251110-rgmii_delay_2600-v4-0-5cad32c766f7@aspeedtech.com Changes in v4: - Remove the compatible "aspeed,ast2600-mac01" and "aspeed,ast2600-mac23" - Add new property to specify the RGMII delay step for each MACs - Add default value of rx/tx-internal-delay-ps - For legacy dts, a warning message reminds users to update phy-mode - If lack rx/tx-internal-delay-ps, driver will use default value to configure the RGMII delay - Link to v3: https://lore.kernel.org/r/20251103-rgmii_delay_2600-v3-0-e2af2656f7d7@aspeedtech.com Changes in v3: - Add new item on compatible property for new compatible strings - Remove the new compatible and scu handle of MAC from aspeed-g6.dtsi - Add new compatible and scu handle to MAC node in aspeed-ast2600-evb.dts - Change all phy-mode of MACs to "rgmii-id" - Keep "aspeed,ast2600-mac" compatible in ftgmac100.c and configure the rgmii delay with "aspeed,ast2600-mac01" and "aspeed,ast2600-mac23" - Link to v2: https://lore.kernel.org/r/20250813063301.338851-1-jacky_chou@aspeedtech.com Changes in v2: - added new compatible strings for MAC0/1 and MAC2/3 - updated device tree bindings to restrict phy-mode and delay properties - refactored driver code to handle rgmii delay configuration - Link to v1: https://lore.kernel.org/r/20250317025922.1526937-1-jacky_chou@aspeedtech.com --- Jacky Chou (4): dt-bindings: net: ftgmac100: Add delay properties for AST2600 ARM: dts: aspeed-g6: add aspeed,scu property for MAC net: ftgmac100: Add RGMII delay support for AST2600 ARM: dts: aspeed: ast2600-evb: Configure RGMII delay for MAC .../devicetree/bindings/net/faraday,ftgmac100.yaml | 27 ++ arch/arm/boot/dts/aspeed/aspeed-ast2600-evb.dts | 20 +- arch/arm/boot/dts/aspeed/aspeed-g6.dtsi | 4 + drivers/net/ethernet/faraday/ftgmac100.c | 288 ++++++++++++++++++++- drivers/net/ethernet/faraday/ftgmac100.h | 25 ++ 5 files changed, 358 insertions(+), 6 deletions(-) --- base-commit: 8f7aa3d3c7323f4ca2768a9e74ebbe359c4f8f88 change-id: 20251031-rgmii_delay_2600-a00b0248c7e6 Best regards, -- Jacky Chou
