[PATCH v4 0/6] Add CPSW2G and CPSW9G nodes for J784S4

From: Chintan Vankar
Date: Wed Jan 31 2024 - 05:15:10 EST


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.
