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. Summary of changes: - dt-bindings: net: ftgmac100: Add conditional schema for AST2600 MAC0/1 and MAC2/3. - ARM: dts: aspeed-g6: Add aspeed,rgmii-delay-ps and aspeed,scu properties. - ARM: dts: aspeed-ast2600-evb: Add rx/tx-internal-delay-ps properties and update phy-mode for MACs. - net: ftgmac100: Add driver support for configuring RGMII delay for AST2600 MACs via SCU. This enables precise RGMII timing configuration for AST2600-based platforms, improving interoperability with various PHYs To: Andrew Lunn To: David S.
