ARM: keystone: Make PM bus ready before populating platform devices (8308a78d) · Commits · 戴 / test

Keystone PM bus makes use of generic PM clock core backend. Since generic PM clock core uses platform bus notifiers to track events like ADD_DEVICE/DEL_DEVICE and to fill clock lists per each device, we need to initialise Keystone PM domains before the platform devices have been created. Hence, fix it by moving keystone_pm_runtime_init() before platform devices have been populated. Reported-by:
