Subject: [PATCH v4 0/5] TI-K3-DTS: Cleanup CPSW DT Nodes

Hello,

This series cleans up the CPSW Device-tree nodes by updating the SoC and
board files to keep CPSW disabled in the SoC files and enable it only in
the board files.

The following is a summary of the SoCs, CPSW instance and the Boards that
this series affects:

-----    -------    ----------------  -------------------------------------------------------------
S.No.      SoC        CPSW Instance                         Board(s) / SOM(s)
-----    -------    ----------------  -------------------------------------------------------------
  1.       AM62          CPSW3G           AM625-Beagleplay, AM62-LP-SK, AM62-Phycore-SOM, AM625-SK
  2.       AM65        MCU CPSW2G         AM654-Base-Board, IOT-2050 Based Boards
  3.       J7200       MCU CPSW2G         J7200-Common-Processor-Board
  4.       J721E       MCU CPSW2G         J721E-Common-Processor-Board, J721E-Beagleboneai64, J721E-SK
  5.       J721S2      MCU CPSW2G         AM68-SK-Base-Board, J721S2-Common-Processor-Board, AM68-Phyboard

Series is based on linux-next tagged next-20251014.

v3 of this series is at:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20251014125349.3408784-1-s-vadapalli@ti.com/
Changes since v3:
- Rebased series on next-20251014.
- Based on feedback from Dominik Haller <d.haller@...tec.de> at:
  https://lore.kernel.org/r/df6acbfe5d30956ed66e2768fa595c36d2ebe98a.camel@phytec.de/
  the first and fifth patch have been updated to enable cpsw in:
  k3-am62-phycore-som.dtsi and k3-am68-phyboard-izar.dts respectively.
- The fourth patch of this series has been updated to enable cpsw in:
  k3-j721e-beagleboneai64.dts and k3-j721e-sk.dts
