What do people think of this? Does it sound like a good idea to go ahead
with a reset subsystem? Should we simply add a new API to the common clock
subsystem instead (and assume that reset and clock domains match 1:1).
Should this be implemented as part of the generic power management domains;
see include/linux/pm_domain.h instead?

Hi Stephen,

I'm not sure a "reset subsystem" is necessary, but I also do not like
using clocks as the keys for IP reset.  I think it is more common to map
IPs to struct device, no?

And of course for clocks shared by multiple users this will not scale.

Mike
