* to the rest of the driver stack (such as a driver that's ON gating off
* clocks which are not in active use).
*
* The externally visible transitions are handled with the help of the following
* callbacks included in this structure:
*
* @prepare: Prepare the device for the upcoming transition, but do NOT change
* its hardware state. Prevent new children of the device from being
* registered after @prepare() returns (the driver's subsystem and
* generally the rest of the kernel is supposed to prevent new calls to the
* probe method from being made too once @prepare() has succeeded). If
* @prepare() detects a situation it cannot handle (e.g. registration of a
* child already in progress), it may return -EAGAIN, so that the PM core
* can execute it once again (e.g. after the new child has been registered)
* to recover from the race condition. This method is executed for all
* kinds of suspend transitions and is followed by one of the suspend
* callbacks: @suspend(), @freeze(), or @poweroff().
* The PM core executes @prepare() for all devices before starting to
* execute suspend callbacks for any of them, so drivers may assume all of
* the other devices to be present and functional while @prepare() is being
* executed. In particular, it is safe to make GFP_KERNEL memory
* allocations from within @prepare(). However, drivers may NOT assume
* anything about the availability of the user space at that time and it
* is not correct to request firmware from within @prepare() (it's too
* late to do that). [To work around this limitation, drivers may
* register suspend and hibernation notifiers that are executed before the
* freezing of tasks.]
*
* @complete: Undo the changes made by @prepare(). This method is executed for
* all kinds of resume transitions, following one of the resume callbacks:
* @resume(), @thaw(), @restore(). Also called if the state transition
* fails before the driver's suspend callback (@suspend(), @freeze(),
* @poweroff()) can be executed (e.g. if the suspend callback fails for one
* of the other devices that the PM core has unsuccessfully attempted to
* suspend earlier).
* The PM core executes @complete() after it has executed the appropriate
* resume callback for all devices.
*
* @suspend: Executed before putting the system into a sleep state in which the
* contents of main memory are preserved. Quiesce the device, put it into
* a low power state appropriate for the upcoming system state (such as
* PCI_D3hot), and enable wakeup events as appropriate.
*
* @resume: Executed after waking the system up from a sleep state in which the
* contents of main memory were preserved. Put the device into the
* appropriate state, according to the information saved in memory by the
* preceding @suspend(). The driver starts working again, responding to
* hardware events and software requests. The hardware may have gone
* through a power-off reset, or it may have maintained state from the
* previous suspend() which the driver may rely on while resuming. On most
* platforms, there are no restrictions on availability of resources like
* clocks during @resume().
*
* @freeze: Hibernation-specific, executed before creating a hibernation image.
* Quiesce operations so that a consistent image can be created, but do NOT
* otherwise put the device into a low power device state and do NOT emit
* system wakeup events. Save in main memory the device settings to be
* used by @restore() during the subsequent resume from hibernation or by
* the subsequent @thaw(), if the creation of the image or the restoration
* of main memory contents from it fails.
*
* @thaw: Hibernation-specific, executed after creating a hibernation image OR
* if the creation of the image fails. Also executed after a failing
* attempt to restore the contents of main memory from such an image.
* Undo the changes made by the preceding @freeze(), so the device can be
* operated in the same way as immediately before the call to @freeze().
*
* @poweroff: Hibernation-specific, executed after saving a hibernation image.
* Quiesce the device, put it into a low power state appropriate for the
* upcoming system state (such as PCI_D3hot), and enable wakeup events as
* appropriate.
*
* @restore: Hibernation-specific, executed after restoring the contents of main
* memory from a hibernation image. Driver starts working again,
* responding to hardware events and software requests. Drivers may NOT
* make ANY assumptions about the hardware state right prior to @restore().
* On most platforms, there are no restrictions on availability of
* resources like clocks during @restore().
*
* All of the above callbacks, except for @complete(), return error codes.
* However, the error codes returned by the resume operations, @resume(),
* @thaw(), and @restore(), do not cause the PM core to abort the resume
* transition during which they are returned. The error codes returned in
* that cases are only printed by the PM core to the system logs for debugging
* purposes. Still, it is recommended that drivers only return error codes
* from their resume methods in case of an unrecoverable failure (i.e. when the
* device being handled refuses to resume and becomes unusable) to allow us to
* modify the PM core in the future, so that it can avoid attempting to handle
* devices that failed to resume and their children.
*
* It is allowed to unregister devices while the above callbacks are being
* executed. However, it is not allowed to unregister a device from within any
* of its own callbacks.

/**
* struct usb_function - describes one function of a configuration
* @name: For diagnostics, identifies the function.
* @strings: tables of strings, keyed by identifiers assigned during bind()
* and by language IDs provided in control requests
* @descriptors: Table of full (or low) speed descriptors, using interface and
* string identifiers assigned during @bind(). If this pointer is null,
* the function will not be available at full speed (or at low speed).
* @hs_descriptors: Table of high speed descriptors, using interface and
* string identifiers assigned during @bind(). If this pointer is null,
* the function will not be available at high speed.
* @config: assigned when @usb_add_function() is called; this is the
* configuration with which this function is associated.
* @bind: Before the gadget can register, all of its functions bind() to the
* available resources including string and interface identifiers used
* in interface or class descriptors; endpoints; I/O buffers; and so on.
* @unbind: Reverses @bind; called as a side effect of unregistering the
* driver which added this function.
* @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
* initialize usb_ep.driver data at this time (when it is used).
* Note that setting an interface to its current altsetting resets
* interface state, and that all interfaces have a disabled state.
* @get_alt: Returns the active altsetting. If this is not provided,
* then only altsetting zero is supported.
* @disable: (REQUIRED) Indicates the function should be disabled. Reasons
* include host resetting or reconfiguring the gadget, and disconnection.
* @setup: Used for interface-specific control requests.
* @suspend: Notifies functions when the host stops sending USB traffic.
* @resume: Notifies functions when the host restarts USB traffic.
*
* A single USB function uses one or more interfaces, and should in most
* cases support operation at both full and high speeds. Each function is
* associated by @usb_add_function() with a one configuration; that function
* causes @bind() to be called so resources can be allocated as part of
* setting up a gadget driver. Those resources include endpoints, which
* should be allocated using @usb_ep_autoconfig().
*
* To support dual speed operation, a function driver provides descriptors
* for both high and full speed operation. Except in rare cases that don't
* involve bulk endpoints, each speed needs different endpoint descriptors.
*
* Function drivers choose their own strategies for managing instance data.
* The simplest strategy just declares it "static', which means the function
* can only be activated once. If the function needs to be exposed in more
* than one configuration at a given speed, it needs to support multiple
* usb_function structures (one for each configuration).
*
* A more complex strategy might encapsulate a @usb_function structure inside
* a driver-specific instance structure to allows multiple activations. An
* example of multiple activations might be a CDC ACM function that supports
* two or more distinct instances within the same configuration, providing
* several independent logical data links to a USB host.

* Composite devices are, by definition, ones with configurations which
* include more than one function.
*
* The lifecycle of a usb_configuration includes allocation, initialization
* of the fields described above, and calling @usb_add_config() to set up
* internal data and bind it to a specific device. The configuration's
* @bind() method is then used to initialize all the functions and then
* call @usb_add_function() for them.
*
* Those functions would normally be independant of each other, but that's
* not mandatory. CDC WMC devices are an example where functions often
* depend on other functions, with some functions subsidiary to others.
* Such interdependency may be managed in any way, so long as all of the
* descriptors complete by the time the composite driver returns from
* its bind() routine.

* (d) configurations that are specific to wireless links;
* (e) function drivers that understand wireless configs and will
* support wireless for (additional) function instances;
* (f) a function to support association setup (like CBAF), not
