The COMMONONN bit turns off the PHY when the host controller puts it into suspend state. This can happen during the following... - Nothing is connected to the port - The host controller goes into low power mode whatever due to auto suspend or system suspend. With COMMONONN we also must unset U2_FREECLK_EXISTS since the UTMI clock is fed by the PHY. With these changes we see a power savings of ~12mW when port is in suspend.

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.
