One way to do it is to introduce a new config option,
CONFIG_COMMON_CLK_DEBUG_CONTROL that would expose the controls for
every clock in the existing debugfs infrastructure. The downside to
this approach is that it would get abused and ship in millions of
Android products using horrible userspace hacks to control clocks.
Maybe that's not our problem to solve, maybe it is.
We already have this for MSM. But I seem to have managed to keep our
userspace guys away from abusing it. YMMV.
It's much harder when it's in the standard kernel and there's no contact
with some of the users. I've pushed back pretty strongly on some of
your equivalent stuff for regulators for this reason.
Agreed. I don't really keep up with what's going on with the MSM regulators.
But at some point, I'll start requesting for this for debugfs. It's
terribly handy to debug power issues, run unit tests and for debug
sessions (debugfs. So, clearly!).
