Neal Frager c0484aa1ad usb: dwc3: xilinx: make sure pipe clock is deselected in usb2 only mode 
commit a48f744bef upstream.

When the USB3 PHY is not defined in the Linux device tree, there could
still be a case where there is a USB3 PHY active on the board and enabled
by the first stage bootloader. If serdes clock is being used then the USB
will fail to enumerate devices in 2.0 only mode.

To solve this, make sure that the PIPE clock is deselected whenever the
USB3 PHY is not defined and guarantees that the USB2 only mode will work
in all cases.

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.
