Olof Johansson pointed out that usually the company name is picked as
namespace prefix to specific properties. So expect "energymicro,location"
but fall back to the previously introduced name "efm32,location".

Applied to for-next, thanks! If you think this is better suited in
for-current, let me know.

I'm not in a hurry. If you take it it's fine for me.

(BTW, I'm not sure i fI understand your branch naming. for-next means
"targeting the next merge window" and for-current means "targeting the
next release"? So for-next currently means 3.17-rc1?)

Thanks
Uwe
