The change in itself is sound, but I don't understand why i2c/spi fails
to function if we don't bring them to a sleep state. Can you please
update the commit message with an explanation?
PS. Whenever there's multiple states for a thing I do prefer prefixing
them _a and _s to highlight that difference (not only suffixing the
sleep state). And use abbreviations :)

Bjorn
