The title should start by ARM: dts: mvebu:

If there is no need to have a v5 then I wil take care of modifying the
title while applying it.

I think we should keep the "marvell,orion-gpio" too because the hardware
is still compatible with it. Morever it will allow to use a recent dtb
with an old kernel.

Same here and for all the others...
