To dump internal LSP and endpoint state debug registers, we must write
to GDBGLSPMUX register. This patch correctly dump LSP and endpoint
states from the debug registers.
If the controller is in device mode, all LSP and endpoint state
registers will be dumped via the debugfs attribute "lsp_dump". In host
mode, the user has to write the LSP number to "lsp_dump" to dump a
specific LSP selection.

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.
