My patch should be good to go, it seem to match the code in latest vendor 5.10 tree.

The vendor tree does contain one additional detection pin for GMAC1 IO mux M1,
GPIO4_B7 (gmac1m1-miim) in addition to the existing GPIO4_A7 (gmac1m1-rx-bus2).
However, I do not see any need for what seem to be a superfluous detection pin,
all in-tree device tree select both gmac1m1-rx-bus2 and gmac1m1-miim.

Best regards,
Jonas
