Sascha,

I know I dropped it, but have you tried empty/bool properties?
I had no luck with an empty/bool ranges, so I removed the 1:1
translation by empty property and wanted to take a look at bool
props first.

Could be that, I was just tired and made a mistake. Will investigate
as soon as Thomas aggrees to my next consolidation patch set.

In general, yes. If you copy the behavior of linux, we should not
try to merge individual base.c, address.c, whatever.c out of drivers/of
into differently named files.
