[PATCH v2 0/2] Add ICSSG0 dual EMAC support for AM642 EVM
Posted by Meghana Malladi 1 month, 2 weeks ago 
This series adds device tree overlay support for enabling ICSSG0 dual EMAC
on the AM642 EVM, along with the necessary PHY driver configuration.

The overlay enables both ICSSG0 Ethernet interfaces (port0 and port1) in
dual EMAC mode and can be combined with the existing ICSSG1 overlay to
enable all four ICSSG interfaces if needed.

The series also enables the DP83TG720 PHY driver required for the
DP83TG720-IND-SPE-EVM daughter card used with the ICSSG0 interface.

Tested both ipv6 and ipv4 ping to be functional with the following 
topology.

DUT 1 eth3 <---> eth2 DUT2

DUT1 log: https://gist.github.com/dao-qiu/f261147110b6b05d1fb989ee74e1d694

DUT2 log: https://gist.github.com/dao-qiu/3add536e2370d6afe36145f46df784e6

You cannot test defconfig, so please don't post it to cover letter. Same
effort for you - one Tb tag - but now you require maintainers to handle
it specially when applying.

Best regards,

Apologies for this, I was not aware the problem with testing defconfig. 
I will keep this in mind when I add the Tb tag in any future patches.
