While collaborating with Benjamin Gaignard to deploy the hierarchical layout
for an ST SoC, it has turned that I have clearly missed to test a couple of
corner cases in recently added support to the cpuidle-psci driver.

This series are fixing the issues we have found.

Ulf Hansson (4):
  PM / Domains: Allow no domain-idle-states DT property in genpd when
    parsing
  cpuidle: psci: Fixup support for domain idle states being zero
  cpuidle: psci: Split psci_dt_cpu_init_idle()
  cpuidle: psci: Allow WFI to be the only state for the hierarchical
    topology
