usb: dwc2: gadget: enable WKUP_ALERT interrupt
Grigor Tovmasyan authored

WKUP_ALERT interrupt should be unmask when lpm mode is enabled.

This interrupt is asserted when the device is in L1 for the duration
mentioned in GREFCLK.SOF_CNN_WKUP_ALERT. This is used to alert SW to
initiate Remote wake up so that the device resumes in time in order not
to lose sync with the host frame number.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
