Kiwoong Kim 2fc01226c2 scsi: ufs: Add a quirk to permit overriding UniPro defaults
[ Upstream commit b1d0d2eb89d4e3a25b212a9d836587503537067e ]

The UniPro specification states that attribute IDs of the following
parameters are vendor-specific so some SoCs could have no regions at the
defined addresses:

 - DME_LocalFC0ProtectionTimeOutVal
 - DME_LocalTC0ReplayTimeOutVal
 - DME_LocalAFC0ReqTimeOutVal

In addition, the following parameters should be set considering the
compatibility between host and device.

 - PA_PWRMODEUSERDATA0
 - PA_PWRMODEUSERDATA1
 - PA_PWRMODEUSERDATA2
 - PA_PWRMODEUSERDATA3
 - PA_PWRMODEUSERDATA4
 - PA_PWRMODEUSERDATA5

Introduce a quirk to allow vendor drivers to override the UniPro defaults.

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.
