The first patch fixes many issues with current task management handling
in UFSHCD driver. Others improve error handling in various scenarios.
These patches depends on:
[PATCH 01/10] scsi: ufs: wrap the i/o access operations
[PATCH 02/10] scsi: ufs: amend interrupt configuration
[PATCH 03/10] scsi: ufs: remove version check before IS reg clear
[PATCH 04/10] scsi: ufs: rework link start-up process
[PATCH 05/10] scsi: ufs: Fix the response UPIU length setting
[PATCH 06/10] scsi: ufs: use devres functions for ufshcd
[PATCH 07/10] ufshcd-pltfrm: add missing empty slot in ufs_of_match[]
[PATCH 08/10] ufs: fix register address in UIC error interrupt handling
[PATCH 09/10] ufshcd-pltfrm: remove unnecessary dma_set_coherent_mask() call
[PATCH 10/10] ufs: fix DMA mask setting
[PATCH V2 1/2] scsi: ufs: Add support for sending NOP OUT UPIU
[PATCH V2 2/2] scsi: ufs: Set fDeviceInit flag to initiate device initialization
[PATCH V2 1/2] scsi: ufs: Add support for host assisted background operations
[PATCH V2 2/2] scsi: ufs: Add runtime PM helpers for UFS host driver
Changes from v1:
- [PATCH V2 1/4]: Fix a race condition because of overloading
outstanding_tasks variable to lock the slots. A new variable
tm_slots_in_use will track which slots are in use by the driver.
- [PATCH V2 2/4]: Commit text update to clarify the hardware race
with more details.
- [PATCH V2 3/4]: Minor cleanup and rebase
- [PATCH V2 4/4]: Fix a bug - sleeping in atomic context
Sujit Reddy Thumma (4):
scsi: ufs: Fix broken task management command implementation
scsi: ufs: Fix hardware race conditions while aborting a command
scsi: ufs: Fix device and host reset methods
scsi: ufs: Improve UFS fatal error handling
