Subject: [PATCH net-next v2 0/3] Add support for J784S4 CPSW9G

Hello,

This series adds a new compatible to am65-cpsw driver for the CPSW9G
instance of the CPSW Ethernet Switch on TI's J784S4 SoC which has 8
external ports and 1 internal host port.

The CPSW9G instance supports QSGMII and USXGMII modes for which driver
support is added.

Additionally, the interface mode specific configurations are moved to the
am65_cpsw_nuss_mac_config() callback. Also, a TODO comment is added for
verifying whether in-band mode is necessary for 10 Mbps RGMII mode.

Changes from v1:
1. Add a patch to move interface mode specific configuration from the
   mac_link_up() callback to the mac_config() callback of the am65-cpsw
   driver. Also, add a TODO comment for 10 Mbps RGMII in-band mode.
2. Add MAC_5000FD to the list of mac_capabilities member unconditionally,
   since the CPSW MAC supports it.
3. Add USXGMII mode specific configuration in the mac_config() callback
   along with the SGMII mode specific configuration, instead of the
   mac_link_up() callback which was incorrectly done in the v1 series.

v1:
https://lore.kernel.org/r/20230331065110.604516-1-s-vadapalli@ti.com/

Regards,
Siddharth.
