subhashj@codeaurora.org 401f1e4490 scsi: ufs: don't suspend clock scaling during clock gating
Currently we are suspending clock scaling during clock gating which doesn't
allow us to have clock gating timeout lower than clock scaling polling
window. If clock gating timeout is smaller than the clock scaling polling
window then we will mostly suspend the clock scaling before clock scaling
polling window expires and we might get stuck in same state (scaled down
or scaled up) for quite a long time. And for this reason, we have clock
gating timeout (150ms) greater than clock scaling polling window (100ms).

We would like to have aggressive clock gating timeout even lower than the
clock scaling polling window hence this change is decoupling the clock
scaling suspend/resume from clock gate/ungate. We will not suspend the
clock scaling as part of clock gating instead clock scaling context will
schedule scaling suspend work if there are no more pending transfer
requests.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
