usb: gadget: composite: add iSerialNumber to usb_composite_driver

2012-05-10T19:22:43+00:00

Add iSerialNumber to usb_composite_driver to allow setting a default value.
This is useful when the module is compiled-in. Then the composite_bind
is executed at kernel boot and string id for iSerialNumber can be overridden
even if there is no iSerialNumber kernel commandline parameter.
If the string id is not overridden, then get_string will never attempt to
look for the alternative string contents using cdev->serial_override.

usb: gadget: composite: Add usb_remove_config

2012-05-10T19:21:32+00:00

Add usb_remove_config to unbind a configuration and remove it from
the configs list. This allows implementing composite gadget drivers that
can disconnect themself from the bus and that will later be re-enumerated
with a different configuration.

Gadget drivers must call usb_gadget_disconnect before calling this
function to disable the pullup, disconnect the device from the host,
and prevent the host from enumerating the device while we are changing
the gadget configuration.

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 max_speed to usb_composite_driver

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

This field is used by the Gadget drivers to specify
the maximum speed they support, meaning: the maximum
speed they can provide descriptors for.

The driver speed will be set in consideration of this
value.

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: composite: Allow function drivers to pause control transfers

2011-05-10T21:14:57+00:00

Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the
data/status stages of standard control requests like SET_CONFIGURATION or
SET_INTERFACE till they are done with their bookkeeping and are actually ready
for accepting new commands to their interface.

They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS
in their setup handlers (e.g. set_alt()). The composite framework will then
defer completion of the control transfer by not completing the data/status stages.

This ensures that the host does not send new packets to the interface till the
function driver is ready to take them.

When the function driver that requested for USB_GADGET_DELAYED_STATUS is done
with its bookkeeping, it should signal the composite framework to continue with
the data/status stages of the control transfer. It can do so by invoking
the new API usb_composite_setup_continue(). This is where the control transfer's
data/status stages are completed and host can initiate new transfers.

The DELAYED_STATUS mechanism is currently only supported if the expected data phase
is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the
only cases that will use this mechanism, this is not a limitation.

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.
