Description: Write/read Option ROM data.
What: /sys/module/ehci_hcd/drivers/.../uframe_periodic_max
Date: July 2011
KernelVersion: 3.1
Contact: Kirill Smelkov <kirr@mns.spb.ru>
Description: Maximum time allowed for periodic transfers per microframe (μs)
[ USB 2.0 sets maximum allowed time for periodic transfers per
microframe to be 80%, that is 100 microseconds out of 125
microseconds (full microframe).
However there are cases, when 80% max isochronous bandwidth is
too limiting. For example two video streams could require 110
microseconds of isochronous bandwidth per microframe to work
together. ]
Through this setting it is possible to raise the limit so that
the host controller would allow allocating more than 100
microseconds of periodic bandwidth per microframe.
Beware, non-standard modes are usually not thoroughly tested by
hardware designers, and the hardware can malfunction when this
setting differ from default 100.

This host controller driver emulates USB, looping all data transfer
requests back to a USB "gadget driver" in the same host. The host
side is the master; the gadget side is the slave. Gadget drivers
can be high, full, or low speed; and they have access to endpoints
like those from NET2280, PXA2xx, or SA1100 hardware.
This may help in some stages of creating a driver to embed in a
Linux device, since it lets you debug several parts of the gadget
driver without its hardware or drivers being involved.
Since such a gadget side driver needs to interoperate with a host
side Linux-USB device driver, this may help to debug both sides
of a USB protocol stack.

* usb_ep_autoconfig - choose an endpoint matching the descriptor

* descriptor and ep companion descriptor
* @gadget: The device to which the endpoint must belong.
* @desc: Endpoint descriptor, with endpoint direction and transfer mode
* initialized. For periodic transfers, the maximum packet
* size must also be initialized. This is modified on
* success.
* @ep_comp: Endpoint companion descriptor, with the required
* number of streams. Will be modified when the chosen EP
* supports a different number of streams.
*
* This routine replaces the usb_ep_autoconfig when needed
* superspeed enhancments. If such enhancemnets are required,
* the FD should call usb_ep_autoconfig_ss directly and provide
* the additional ep_comp parameter.
*
* By choosing an endpoint to use with the specified descriptor,
* this routine simplifies writing gadget drivers that work with
* multiple USB device controllers. The endpoint would be
* passed later to usb_ep_enable(), along with some descriptor.
*
* That second descriptor won't always be the same as the first one.
* For example, isochronous endpoints can be autoconfigured for high
* bandwidth, and then used in several lower bandwidth altsettings.
* Also, high and full speed descriptors will be different.
*
* Be sure to examine and test the results of autoconfiguration
* on your hardware. This code may not make the best choices
* about how to use the USB controller, and it can't know all
* the restrictions that may apply. Some combinations of driver
* and hardware won't be able to autoconfigure.
*
* On success, this returns an un-claimed usb_ep, and modifies the endpoint
* descriptor bEndpointAddress. For bulk endpoints, the wMaxPacket value
* is initialized as if the endpoint were used at full speed and
* the bmAttribute field in the ep companion descriptor is
* updated with the assigned number of streams if it is
* different from the original value. To prevent the endpoint
* from being returned by a later autoconfig call, claim it by
* assigning ep->driver_data to some non-null value.
*
* On failure, this returns a null endpoint descriptor.
