[ Upstream commit af076a41f8a28faf9ceb9dd2d88aef2c202ef39a ] It is possible that the gadget will be disabled, while the udc is suspended. When enabling the udc in that case, the clock gating will not be enabled again. Leaving the phy unclocked. Even when the udc is not enabled, connecting this powered but not clocked phy leads to enumeration errors on the host side. To ensure that the clock gating will be in an valid state, we ensure that the clock gating will be enabled before stopping the udc.

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.
