usb gadget: don't save bind callback in struct usb_configuration

2010-10-22T17:21:26+00:00

The bind function is most of the time only called at init time so there
is no need to save a pointer to it in the configuration structure.

This fixes many section mismatches reported by modpost.

USB: gadget: composite: Better string override handling

2010-10-22T17:21:23+00:00

The iManufatcurer, iProduct and iSerialNumber composite module
parameters were only used when the gadget driver registers
strings for manufacturer, product and serial number.  If the
gadget never bothered to set corresponding fields in USB device
descriptors those module parameters are ignored.

This commit makes the parameters work even if the strings ID
have not been assigned.  It also changes the way IDs are
overridden -- what IDs are overridden is now saved in
usb_composite_dev structure -- which makes it unnecessary to
modify the string tables the way previous code did.

The commit also adds a iProduct and iManufatcurer fields to the
usb_composite_device structure.  If they are set, appropriate
strings are reserved and added to device descriptor.  This makes
it unnecessary for gadget drivers to maintain code for setting
those.  If iProduct is not set it defaults to
usb_composite_device::name; if iManufatcurer is not set
a default "  with " is used.

The last thing is that if needs_serial field of
usb_composite_device is set and user failed to provided
iSerialNumber parameter a warning is issued.

USB: gadget: composite: added disconnect callback

2010-08-10T21:35:37+00:00

Added a disconnect() callback to composite devices which
is called by composite glue when its disconnect callback
is called by gadget.

USB: gadget: composite: usb_string_ids_*() functions added

2010-08-10T21:35:36+00:00

usb_string_ids_tab() and usb_string_ids_n() functions added to
the composite framework.  The first accepts an array of
usb_string object and for each registeres a string id and the
second registeres a given number of ids and returns the first.

This may simplify string ids registration since gadgets and
composite functions won't have to call usb_string_id() several
times and each time check for errer status -- all this will be
done with a single call.

USB gadget: Handle endpoint requests at the function level

2009-12-11T19:55:15+00:00

Control requests targeted at an endpoint (that is sent to EP0 but
specifying the target endpoint address in wIndex) are dispatched to the
current configuration's setup callback, requiring all gadget drivers to
dispatch the requests to the correct function driver.

To avoid this, record which endpoints are used by each function in the
composite driver SET CONFIGURATION handler and dispatch requests
targeted at endpoints to the correct function.

USB: gadget: composite device-level suspend/resume hooks

2009-03-24T23:20:45+00:00

Address one open question in the composite gadget framework:
Yes, we should have device-level suspend/resume callbacks
in addition to the function-level ones.  We have at least one
scenario (with gadget zero in OTG test mode) that's awkward
to handle without it.
