commit 27f94b71532203b079537180924023a5f636fca1 upstream.
2290 was found in the field to also require this quirk, as long &
high-bandwidth workloads (e.g. USB ethernet) are consistently able to
crash the controller otherwise.
The same change has been made for a number of SoCs in [1], but QCM2290
somehow escaped the list (even though the very closely related SM6115
was there).
Upon a controller crash, the log would read:
xhci-hcd.12.auto: xHCI host not responding to stop endpoint command
xhci-hcd.12.auto: xHCI host controller not responding, assume dead
xhci-hcd.12.auto: HC died; cleaning up
Add snps,parkmode-disable-ss-quirk to the DWC3 instance in order to
prevent the aforementioned breakage.

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.
