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

I've rebased on net-next this morning. I just checked again and now
there is a conflict indeed. Something got applied between in the last 6
ours which conflict with patch 4.

OK

Agreed. The change is provided here so people can test.
If the other patches get accepted, I'll submit the dts change through
the amlogic tree.
