Ulf Hansson 2bc12a8199 pmdomain: rockchip: Fix regulator dependency with GENPD_FLAG_NO_STAY_ON ... The deferred regulator retrieval for Rockchip PM domains are causing some weird dependencies. More precisely, if the power-domain is powered-on from the HW perspective, its corresponding regulator must not be powered-off via regulator_init_complete(), which is a late_initcall_sync. Even on platforms that don't have the domain-supply regulator specified for the power-domain provider, may suffer from these problems. More precisely, things just happen to work before, because genpd_power_off_unused() (also a late_initcall_sync) managed to power-off the PM domain before regulator_init_complete() powered-off the regulator. Ideally this fragile dependency must be fixed properly for the Rockchip PM domains, but until then, let's fallback to the previous behaviour by using the GENPD_FLAG_NO_STAY_ON flag.
