Hi all,

Below is a current list of ARM boards with more than 40 dtc warnings
when building with W=1. There's a treewide patch in flight to fix some
unit-address warnings[1], so those aren't included here. The list is
grouped by maintainer. AT91, Exynos, and Allwinner continue to be at
the top of the list and have been for some time (though having
multiple boards for an SoC can cause lots of duplicated warnings).

Please help fix these. More checks are being added[2].

For the at91 ones, IIRC, they are coming from the clock binding and we
will have to break the ABI to fix it. This is not something we wanted to
do before 4.14 but it will happen at some point.

Looks like they are just missing unit-address. How does adding a
unit-address break the ABI? Though, aren't you planning to change from
a node per clock to clock controller node(s)? If so, then fixing when
doing that is fine.
