Since commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for
RGMII mode") the networking is broken on the BeagleBone AI which has
the AR8035 PHY for Gigabit Ethernet [0]. The fix is to switch from
phy-mode = "rgmii" to phy-mode = "rgmii-rxid".
Note: Grygorii Strashko made a similar phy-mode fix in 820f8a870f65 for
other AM5729 boards.

Pls change fixed tag to
520557d4854b ARM: dts: am5729: beaglebone-ai: adding device tree
as this board DTB was merged only in 5.8.

Do you mean commit ref 820f8a870f65 ?
("ARM: dts: am57xx: fix networking on boards with ksz9031 phy")
I thought it made sense to point to that commit as you seemed to be
fixing a very similar issue, just for a different phy.
Or did you mean commit ref cd28d1d6e52e ?
("net: phy: at803x: Disable phy delay for RGMII mode")
I believe this is the commit that made it necessary to change the
phy-mode property for the AR8035 PHY.

Yes. but you should use proper format for commit ref:
commit <12+ chars of sha1> (\"<title line>\")'
checkpatch should warn you.
