Jack Pham 82dc6471a5 usb: dwc3: Keep track of interrupt statistics
This change adds debug support to log all received different
events with endpoint0, other endpoints and gadget events. It
tracks these events per endpoint and displays the same.

For each of the endpoint event counters, add the rate (in Hz)
at which it occurs in order to better analyze performance and
aid in optimization.

How to use:
  - Mount debugfs
  - To see received all dwc3 events/interrupts
	cat /sys/kernel/debug/<base_address>.dwc3/int_events
  - To clear all received dwc3 events/interrupts
	echo 0 > /sys/kernel/debug/<base_address>.dwc3/int_events

README

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.
