usb: gadget: udc-core: add "new-style" registration interface

2011-07-01T21:31:13+00:00

udc_start() should only trigger the internal state machine and make
minimal house keeping. Before that call udc-core calls the bind()
callback and after the callback the pullup().

udc_stop() is simillar, udc-core calls pullup(), unbind() and finally
udc_stop().

usb: gadget: add missing #include's

2011-07-01T21:31:05+00:00

When #include'd alone, 
causes a lot of compilation errors and warnings
-- all because it relies on the including code to
bring in the necessary #include's instead of
doing this itself.

usb: gadget: add SuperSpeed support to the Gadget Framework

2011-07-01T21:27:05+00:00

SuperSpeed USB has defined a new descriptor, called
the Binary Device Object Store (BOS) Descriptor. It
has also changed a bit the definition of SET_FEATURE
and GET_STATUS requests to add USB3-specific details.

This patch implements both changes to the Composite
Gadget Framework.

usb: gadget: add streams support to the gadget framework

2011-06-28T18:20:15+00:00

This patch defines necessary fields to support
streaming for USB3.0.

It implements a new function, called
usb_ep_autoconfig_ss(), to be used instead of the
existing usb_ep_autoconfig() when working in
SuperSpeed mode and there is a need to search for
an endpoint according to the number of required
streams.

usb: gadget: use config_ep_by_speed() instead of ep_choose()

1. ep_choose()
2. usb_find_endpoint()

usb: gadget: configure endpoint according to gadget speed

2011-06-28T18:14:36+00:00

Add config_ep_by_speed() to configure the endpoint
according to the gadget speed.

Using this function will spare the FDs from handling
the endpoint chosen descriptor.

usb: gadget: add usb_endpoint_descriptor to struct usb_ep

2011-06-28T18:14:36+00:00

Change usb_ep_enable() prototype to use endpoint
descriptor from usb_ep.

This optimization spares the FDs from saving the
endpoint chosen descriptor. This optimization is
not full though. To fully exploit this change, one
needs to update all the UDCs as well since in the
current implementation each of them saves the
endpoint descriptor in it's internal (and extended)
endpoint structure.

usb: gadget: introduce UDC Class

2011-06-28T18:12:51+00:00

this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.

Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.

As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.

The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

usb gadget: fix all Section mismatch warnings

2011-04-13T23:31:12+00:00

Fix 41 occurrences of this type of Section mismatch warning
in g_mass_storage, g_serial, g_cdc, g_multi, g_nokia, g_ether, g_ffs:
(the 75 number reported earlier contained some duplicates.)

WARNING: drivers/usb/gadget/g_mass_storage.o(.text+0x687a): Section mismatch in reference from the function fsg_bind() to the function .devinit.text:usb_ep_autoconfig()
The function fsg_bind() references
the function __devinit usb_ep_autoconfig().
This is often because fsg_bind lacks a __devinit
annotation or the annotation of usb_ep_autoconfig is wrong.

Also remove __devinit from usb_ep_autoconfig_reset() to prevent
possible section mismatch problems with it.
