Thanks, applied now!

It might be a bit messy to deal with a few things when you split between board
files and DT. In general you might be interested in looking at the syscon
bindings which tend to be used when there are "misc" registers on a SoC that
multiple drivers need to share.


See Documentation/devicetree/bindings/mfd/syscon.txt and other drivers and
platforms for examples of that.
