Hello,
This series adds devicetree node for MAIN CPSW2G instance of CPSW
Ethernet Switch on TI's J721S2 SoC. Also, a devicetree overlay is added
in order to enable MAIN CPSW2G in RGMII-RXID mode using the GESI
Expansion Board connected to the J7 Common-Processor-Board.
NOTE: This series applies on top of the following series:
https://lore.kernel.org/r/[email protected]/
which in turn has been applied on linux-next tagged next-20230525.
Regards,
Siddharth.
