Awesome! Thanks for your work on this.

I've tested this on a orangepi-one. You can add my:

Tested-by: Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

For the next version of this series.

Attached is a dts patch for adding support
for the emac one that one (to be applied on top of this patch-set).

I've a Orange PI Plus and a Orange PI 2 as well, both of which use an external
phy, I would love to test on those as well, do you've a tree with adds the
necessary regulator bits and an example of how this would like in dts
somewhere ?

One remark about:
[PATCH 5/5] ARM: dts: sun8i: Enable sun8i-emac on the Orange PI PC

We always keep the nodes in board.dts files sorted alphebetically,
so the emac node should be after the ehci node rather then at the end.

Regards,

Hans

Subject: [PATCH v3] ARM: dts: sun8i: Enable sun8i-emac on the Orange PI One

The sun8i-emac hardware is present on the Orange PI One.
It uses the internal PHY.

This patch create the needed emac and phy nodes.
