Error handling in UFS driver is broken and resets the host controller
for fatal errors without re-initialization. Correct the fatal error
handling sequence according to UFS Host Controller Interface (HCI)
v1.1 specification.
o Processed requests which are completed w/wo error are reported to
SCS
The first patch fixes many issues with current task management handling
in UFSHCD driver. Others improve error handling in various scenarios.
These patches are rebased on:
[PATCH 9/9] drivers/scsi/ufs: don't check resource with devm_ioremap_resource
Changes from v4:
- Addressed comments f
As of now SCSI initiated error handling is broken because,
the reset APIs don't try to bring back the device initialized and
ready for further transfers.
In case of timeouts, the scsi error handler takes care of handling aborts
and resets. Improve the error handling in such scenario by resetting t

There is a possible race condition in the hardware when the abort
command is issued to terminate the ongoing SCSI command as described
below:
- A bit in the door-bell register is set in the controller for a
new SCSI command.
- In some rare situations, before controller get a chance to issue

Currently, sending Task Management (TM) command to the card might
be broken in some scenarios as listed below:
Problem: If there are more than 8 TM commands the implementation
returns error to the caller.
Fix: Wait for one of the slots to be emptied and send the command.
Problem: Som
