Vishal Badole 888a44f261 clk: Show active consumers of clocks in debugfs 
[ Upstream commit dcce5cc782 ]

This feature lists the clock consumer's name and respective connection
id. Using this feature user can easily check that which user has
acquired and enabled a particular clock.

Usage:
>> cat /sys/kernel/debug/clk/clk_summary
                      enable  prepare  protect
                                                                          duty  hardware                            Connection
   clock               count    count    count    rate   accuracy phase  cycle    enable   consumer                         Id

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.
