A gap:
On OMAP, bus control is independent of CPU frequency control,
so cpufreq and cpuidle don't quite fit the bill.
Perhaps a "bus-idle" analogous to "cpu-idle" may be appropriate?
FWIW this applies to a bunch of other embedded processors too - OMAP
isn't particularly unique here, though it's one of the furthest along in
terms of exploting this in mainline Linux.
This capability would benefit MSM as well. We're looking into a
soc-specific implementation using Pat Pannuto's "pseudo" platform bus
extensions (discussed here http://lkml.org/lkml/2010/8/10/389). After
we have something working, I would be curious to see if some common
functionality could be extracted into a more generic mechanism.
