imx6sx-sabresd also uses an AR8031 Ethernet PHY.

I also tested that changing the phy-mode to "rgmii-id" fixes Ethernet
on pico-imx7d with AR8035.

So yes, we currently have lots of broken dtb's in mainline and I am
wondering what is the proper fix here.

Does anyone know what was the kernel commit that introduced such regressions?
