I've tested this hand-applied because it applies to neither amlogic
v4.10/integ nor linux-next.git and will conflict if applied through the
net-next tree.

Note that there already is an &ethmac node that you should be extending
rather than duplicating:

&ethmac {
	status = "okay";
	pinctrl-0 = <&eth_rgmii_pins>;
	pinctrl-names = "default";
};

If you or your colleagues could please fix the sort order of the nodes
to be alphabetical again (ethmac after i2c_A here; between uart_A and ir
in-tree) this wouldn't happen so easily again.

I therefore suggest to not apply this patch 4/4 through net-next but
through the amlogic tree instead.

Thanks,
Andreas
