Resolve USB 3.0 gadget failure for QM and QXPB0 in super speed mode with
single IN and OUT endpoints, like mass storage devices, due to incorrect
ACTUAL_MEM_SIZE in ep_cap2 (32k instead of actual 18k). Implement dt
property cdns,on-chip-buff-size to override ep_cap2 and set it to 18k for
imx8QM and imx8QXP chips. No adverse effects for 8QXP C0.

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.
