Runtime PM is not supported while USB PHY can be turned off from register accesses. Add runtime PM for the USB2.0 PHY. The PHY is entirely shut down to save as much power as possible. This means that gadgets will not be discovered once suspend state is entered, and suspend state can not be left without an explicit user intervention (through sysfs). That's why runtime PM is disabled by default.

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 reStructuredText 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.
