Mainline Linux tree for various devices, only for fun :)

To recover non-fatal errors, no full reset is required, err_handler only clears those pending TRs/TMRs so that SCSI layer can re-issue them. In current err_handler, TRs are directly cleared from UFS host's doorbell but not aborted from device side. However, according to the UFSHCI JEDEC spec, the host software shall use UTP Transfer Request List Clear Register to clear a task from UFS host's doorbell only when a UTP Transfer Request is expected to not be completed, e.g. when the host software receives a “FUNCTION COMPLETE” Task Management response which means a Transfer Request was aborted. To follow the UFSHCI JEDEC spec, in err_handler, abort one TR before clearing it from doorbell.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
