Hi!

Correct me if I'm wrong, but patches 1-2 aren't strictly necessary for 
OrangePi 3, right? H6 DTSI already has emac node with dual compatible (H6 and 
A64) and since OrangePi 3 uses gigabit ethernet, quirk introduced by patches 
1-2 are not needed.

However, it is nice to have this 100 Mbit fix, because most STB DTS will need 
it.

Best regards,
Jernej
