Ah, I see. I missed the "macirq" name in the binding, but the clock name
must be documented in the binding first. I see that it is present in
Documentation/devicetree/bindings/net/allwinner,sun7i-a20-gmac.txt, but
not in any of the other bindings. The driver however prints out a warning
if it's not present.
I've added this part to my patch now.
