 * drop original patch 1 & 5.
   Patch 5 will be re-sent later when dependent patches merged.
v1->v2:
 * squash a few patches
 * rebase to devfreq-testing


Dong Aisheng (4):
  PM / devfreq: Use more accurate returned new_freq as resume_freq
  PM / devfreq: Remove the invalid description for get_target_freq
  PM / devfreq: bail out early if no freq changes in devfreq_set_target
  PM / devfreq: imx8m-ddrc: remove imx8m_ddrc_get_dev_status
