usb: gadget: android: Update android gadget driver

2011-12-01T05:38:41+00:00

* Functions and the device descriptor are configured from user space:
echo 0       > /sys/class/android_usb/android0/enable
echo adb,acm > /sys/class/android_usb/android0/functions
echo 2       > /sys/class/android_usb/android0/f_acm/instances
echo 1       > /sys/class/android_usb/android0/enable

* Driver does not require platform data anymore

* Moved function initialization to android.c instead of each
function file

* Replaced switches by uevents

usb: gadget: composite: Add usb_remove_config

2011-12-01T05:38:41+00:00

This allows composite drivers to dynamically change their configuration.
For example, a driver might remove a configuration and register a new
one with a different set of functions.
User should prevent the host from enumerating the device while changing
the configuration:

	usb_gadget_disconnect(cdev->gadget);
	usb_remove_config(cdev, old_config);
	usb_add_config(cdev, new_config, new_conf_bind);
	usb_gadget_connect(cdev->gadget);

USB: gadget: composite: Use separate switches for connected and config state

2011-12-01T05:38:09+00:00

Also remove disconnect debouncing, which didn't actually work on some platforms

USB: composite: Add usb_composite_force_reset utility to force enumeration

2011-12-01T05:38:07+00:00

Use this rather than calling usb_gadget_disconnect and usb_gadget_connect
directly to avoid sending USB disconnect events to userspace when resetting
the bus.

USB: gadget: composite: Add userspace notifications for USB state changes

2011-12-01T05:38:06+00:00

Add switch to notify current USB configuration.  This can be used to detect
USB connect and disconnect events.

Broadcast a change via the usb_composite class when a USB function is
enabled or disabled.

Rename usb_function.hidden to usb_function.disabled.

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.
