Manish Pandey 42d15918da scsi: ufs: Introduce quirk to extend PA_HIBERN8TIME for UFS devices
[ Upstream commit 569330a34a31a52c904239439984a59972c11d28 ]

Samsung UFS devices require additional time in hibern8 mode before
exiting, beyond the negotiated handshaking phase between the host and
device.  Introduce a quirk to increase the PA_HIBERN8TIME parameter by
100 µs, a value derived from experiments, to ensure a proper hibernation
process.

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.
