Subject: [RFC PATCH 0/3] Add CPSW9G DT support for J784S4

Hello,

This series adds device-tree nodes for 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.

This series is based on top of the following series:
https://lore.kernel.org/r/20230425131607.290707-1-j-choudhary@ti.com/

This series also depends on the patch for Serdes Mux Bindings at:
https://lore.kernel.org/r/20230310111630.743023-1-s-vadapalli@ti.com/
for patches 2/3 and 3/3.

Regards,
Siddharth.
