it.

When a function is added to a configuration with usb_add_function(), the
configuration speed flags are updated. These flags indicate for which
speeds the configuration is valid for.
This patch adds a flag in the configuration for SuperSpeedPlus and
also updates this based on the existence of ssp_descriptors.

Add a ssp_descriptors member to struct usb_function and handle the
initialization and cleanup of it. This holds the SuperSpeedPlus
descriptors for a function that supports SuperSpeedPlus. This is added
by usb_assign_descriptors().

Add the 'ssp_descriptors' parameter to the usb_assign_descriptors()
function. This allows a function driver to add descriptors for
SuperSpeedPlus speeds if it supports it.
Also update all uses of this function in the gadget subsystem so that
they pass NULL for the ssp_descriptors parameters.

If a gadget supports SuperSpeedPlus or higher speeds, return a
SuperSpeedPlus USB Device Capability descriptor.
Currently this implementation returns a fixed descriptor with typical
values set.

The USB 3.1 specification replaces the USB 3.0 specification and all new
devices that are running at SuperSpeed or higher speeds must report a
bcdUSB of 0x0310.
Refer to USB 3.1 Specification, Revision 1.0, Section 9.6.

The index variable of list_for_each_entry_safe is an offset from a list

PCI-SIG has defined Interface FEh for Base Class 0Ch, Sub-Class 03h as "USB
Device (not host controller)". It is already being used in various USB
device controller drivers for matching, so add PCI_CLASS_SERIAL_USB_DEVICE
and use it.

Otherwise it can work incorrectly.

Converting tcm to the new function interface requires converting
USB tcm's function code and its users.
This patch converts the f_tcm.c to the new function interface.
The file can be now compiled into a separate module usb_f_tcm.ko.
The old function interface is provided by means of preprocessor conditional
directives. After all users are converted, the old interface can be
removed.

usb: patches for v4.5
A ton of improvements to dwc2 have been made. The
driver should be a lot more stable on v4.5 then ever
before.
Our good old dwc3 got a few cleanups and misc fixes
and also added support to Xilinx's integration of
this IP.
Yoshihiro Shimoda gives us support for a new USB3
peripheral controller from Renesas.
Other than these, the usual misc fixes all over the
place.

- Supports super, high and full speed
- Contains 30 pipes for bulk or interrupt transfer
- Contains dedicated DMA controller
This driver doesn't support the dedicated DMAC for now.

It dose not work when we want to use the usb-to-serial port based
on one usb gadget as a console. Thus this patch adds the console
initialization to support this request.
To avoid the re-entrance when transferring data with usb endpoint,
it introduces a kthread to do the IO transmission.

The gadget ethernet driver supports changing the MTU, but only allows this
when the USB cable is removed. The comment indicates that this is because
the "peer won't know". Even if the network link is still down and only the
USB link is established, the driver won't allow the change.
Other network interfaces allow changing the MTU any time, and don't force
the link to be disabled. This makes perfect sense, because in order to be
able to negotiate the MTU, the link needs to be up.
Remove the restriction so that it is now actually possible to change the
MTU (e.g. using "ifconfig usb0 mtu 15000") without having to manually pull
the plug or change the driver's default setting.
This is especially important after commit bba787a860fa

This patch introduces pre-allocation of IN endpoint USB requests. This
improves on latency (requires no usb request allocation on transmit) and avoid
several potential probles on allocating too many usb requests (which involves
DMA pool allocation problems).
This implementation also handles better multiple MIDI Gadget ports, always
processing the last processed MIDI substream if the last USB request wasn't
enought to handle the whole stream.

Change behavior during registration of gadgets and
gadget drivers in udc-core. Instead of previous
approach when for successful probe of usb gadget driver
at least one usb gadget should be already registered
use another one where gadget drivers and gadgets
can be registered in udc-core independently.
Independent registration of gadgets and gadget drivers
is useful for built-in into kernel gadget and gadget
driver case - because it's possible that gadget is
really probed only on late_init stage (due to deferred
probe) whereas gadget driver's probe is silently failed
on module_init stage due to no any UDC added.
Also it is useful for modules case - now there is no
difference what module to insert first: gadget module
or gadget driver one.
