Subject: [PATCH v5 0/3] PM: domains: Detach on device_unbind_cleanup()

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Hi,

Series drops the dev_pm_domain_detach() from platform bus remove and
adds it in device_unbind_cleanup() to avoid runtime resumming the device
after it was detached from its PM domain.

Please provide your feedback.

Thank you,
Claudiu

Changes in v5:
- added PD_FLAG_ATTACH_POWER_ON, PD_FLAG_DETACH_POWER_OFF;
  due to this a new patch was introduced
  "PM: domains: Add flags to specify power on attach/detach"

Changes in v4:
- added a flag in dev_pm_info that is saved in dev_pm_domain_attach()
  and used in device_unbind_cleanup()

Changes in v3:
- add devm_pm_domain_attach()

Changes in v2:
- dropped the devres group open/close approach and use
  devm_pm_domain_attach()
- adjusted patch description to reflect the new approach
