I principle, i agree. However, i'm not too sure about mach-orion5x &
mach-mv78xx0. orion5x has probably been broken since -rc1 was released
and nobody noticed. In the same time, we got around 5 people
independently reporting kirkwood was broken. We have not received any
new boards for orion5x in the time i've been looking at Orion
platforms. mv78xx0 only has one board which is not a Marvell reference
design. So im tempted to not spend any effort moving orion5x or
mv78xx0 to DT unless these actually hinder the effort of moving the
others to DT.  What may make sense is to flatten mv78xx0 and orion5x
into plat-orion and then just watch the bit-rot happen.

I have patches which convert all existing DT based kirkwood boards to
the new gpio/pinctrl code. There are two outstanding issues:

1) I've no idea which kirkwood variant each board uses. Hence the
   compatibility string will be wrong for a lot of them.

2) I'm probably made lots of dumb typos.

So we need to get board maintainers to complete and test the work.

Have you looked at the orion5x PCI code? Its very different to all the
others and i doubt it will be easy to make work with all the others.
