It makes little sense to use generic power domains without runtime PM.
Does it? It still powers down the PM domains on system suspend (at least on my boards ;-)
Sure, but your devices are also using runtime PM, so I'm not sure how does that change my statement above?
I do mean with CONFIG_PM_RUNTIME turned off.
If PM domain support is disabled, s2ram will not power down the PM domains.
But if PM_RUNTIME is enabled along with it, I don't think it will make much of a different, will it?
Building the kernel with genpd and without PM_RUNTIME is possible today, but is it really useful? To me, it only seems to make people try to reinvent the wheel "because PM_RUNTIME may be unset".
I have to say I'm seriously considering to make PM_SLEEP select PM_RUNTIME too as that would make quite a few things a *lot* simpler.
Yes.
If that were the case, we woudn't need the pm_runtime_force_* calls either.
