Jonathan Bell 1f031a0d45 usb: dwc2: masquerade split-interrupt transfers
Masquerading Interrupt split transfers as Control puts the transfer into
the non-periodic handler in the hub. This stops the hub dropping
complete-split data in the microframe after a CSPLIT should have
arrived, improving resilience to host IRQ latency. Devices are none
the wiser - the handshake tokens are the same.

Originally devised by Hans Petter Selasky @ FreeBSD.

(v2: dwc2 needs an un-masquerade prior to channel interrupt handling)

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.
