[PATCH v2 0/3] change UIC command handling

Posted by Kiwoong Kim 2 years, 8 months ago

v1 -> v2: remove an unused variable in __ufshcd_send_uic_cmd

There are two issues on UIC command handling related to auto hibern8.

https://lore.kernel.org/linux-scsi/1684209152-115304-1-git-send-email-kwmad.kim@samsung.com/

Now I combine the two things into this thread.
And one thing added to make part of submitting a UIC command apart
from the critical section w/ host_lock.

Kiwoong Kim (3):
  ufs: make __ufshcd_send_uic_cmd not wrapped by host_lock
  ufs: poll HCS.UCRDY before issuing a UIC command
  ufs: poll pmc until another pa request is completed
