dwc3 allocates scratch and event buffers in the top-level driver. Hack the probe function to set the DMA mask before trying to allocate these. I think the event buffers are only used in device mode, but the scratch buffers may be used if core hibernation is enabled. usb: dwc3: add support for new DT quirks Apply the optional axi-pipe-limit and dis-in-autoretry-quirk properties during driver probe.

If a "usb" alias with the instance number is specified, then use that to construct the device name instead of autogenerating one.

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.
