Well, until we've introduced Pins we're not there at all :-)
Also a coherent infrastructure for defining and using more complicated
interfaces than 'raise/lower' would be good, Pin is just the degenerate
special case of that. That would let us get rid of the annoying
pointer properties we're using for omap clocks, for instance.
