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.

+ * size must also be initialized. This is modified on
+ * success.
+ * @ep_comp: Endpoint companion descriptor, with the required

+ * 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.

- The most notable feature of USB OTG is support for a

- or a host. The initial role choice can be changed
- later, when two dual-role devices talk to each other.
-
- At this writing, the OTG support in this driver is incomplete,
- omitting the mandatory HNP or SRP protocols. However, some
- of the cable based role switching works. (That is, grounding
- the ID pin switches the controller to host mode, while leaving
- it floating leaves it in peripheral mode.)
-
- Select this if your system has a Mini-AB connector, or
- to simplify certain kinds of configuration.
