This series adds device-tree nodes for CPSW2G and CPSW9G instance of the CPSW Ethernet Switch on TI's J784S4 SoC. Additionally, two device-tree overlays are also added: 1. QSGMII mode with the CPSW9G instance via the ENET EXPANSION 1 connector. 2. USXGMII mode with MAC Ports 1 and 2 of the CPSW9G instance via ENET EXPANSION 1 and 2 connectors, configured in fixed-link mode of operation at 5Gbps link speed. Similar to Andrew Davis patch at: https://lore.kernel.org/r/20231117222930.228688-5-afd@xxxxxx/ for J721E, similar changes are also required for J784S4 to remove dependency on the parent node being a syscon node. This series combines the v1 series at: https://lore.kernel.org/r/20230522092201.127598-1-s-vadapalli@xxxxxx/ and the patch for Main CPSW2G node that is present in [PATCH v6 2/5] at: https://lore.kernel.org/r/20230721132029.123881-1-j-choudhary@xxxxxx/ but dropped in it's next version at: https://lore.kernel.org/r/20231019054022.175163-1-j-choudhary@xxxxxx/ Link to v3: https://lore.kernel.org/r/20240125100501.4137977-1-c-vankar@xxxxxx/ Changes from v3 to v4: 1. Add alias for MCU CPSW2G node. 2. Add alias for Main CPSW2G node. 3. Add "ti,mac-only" property for CPSW9G node.
