It has been reported on IRC and in KernelCI boot tests, this change breaks internal PHY support on the Amlogic G12A/SM1 Based boards. We suspect the added signal to reset more than the Ethernet MAC but also the MDIO/(RG)MII mux used to redirect the MAC signals to the internal PHY. This reverts commit f3362f0c18174a1f334a419ab7d567a36bd1b3f3 while we find and acceptable solution to cleanly reset the Ethernet MAC.
