This is fixed with the patch series (yet to be applied upstream) in the link below.

Hi,

After the merge of 5.15.y into net-next, MT7621 ethernet
(mtk_eth_soc.c) does not get probed at all.

Kernel log before 5.15 merge:

I tried adding debug prints into the .mtk_probe function, but it did
not execute.
There are no dts changes for MT7621 between 5.14 and 5.15, so I
believe it should be something else.

Any ideas?
