[PATCH v4 0/3] Simplify and optimize the UFS driver

[Bart Van Assche <bvanassche@xxxxxxx>]

Hello Martin,

This patch series that simplifies and optimizes the UFS driver. Please consider
this patch series for kernel v5.5.

Thanks,

Bart.

Changes compared to v3:
- Left out "scsi" from the name of the functions that suspend and resume
  command processing.

Changes compared to v2:
- Use a separate tag set for TMF tags.

Changes compared to v1:
- Use the block layer tag infrastructure for managing TMF tags.

Bart Van Assche (3):
  ufs: Avoid busy-waiting by eliminating tag conflicts
  ufs: Use blk_{get,put}_request() to allocate and free TMFs
  ufs: Simplify the clock scaling mechanism implementation
