An even more exciting problem exists when a CPU is in the same domain as
other peripherals, those peripherals are all idle and the power domain
is gated. :)

We do have pm_genpd_attach_cpuidle() and pm_genpd_name_attach_cpuidle()?

Exactly.  

And I think to solve this problem, we need to generalize the attaching
of dependent devices to a PM domain.
