- * This file holds USB constants and structures that are needed for
- * USB device APIs. These are used by the USB device model, which is
- * defined in chapter 9 of the USB 2.0 specification and in the
- * Wireless USB 1.0 (spread around). Linux has several APIs in C that
- * need these:
- *
- * - the master/host side Linux-USB kernel driver API;
- * - the "usbfs" user space API; and
- * - the Linux "gadget" slave/device/peripheral side driver API.
- *
- * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
- * act either as a USB master/host or as a USB slave/device. That means
- * the master and slave side APIs benefit from working well together.
- *
- * There's also "Wireless USB", using low power short range radios for
- * peripheral interconnection but otherwise building on the USB framework.
- *
- * Note all descriptors are declared '__attribute__((packed))' so that:
- *
- * [a] they never get padded, either internally (USB spec writers
- * probably handled that) or externally;
- *
- * [b] so that accessing bigger-than-a-bytes fields will never
- * generate bus errors on any platform, even when the location of
- * its descriptor inside a bundle isn't "naturally aligned", and
- *
- * [c] for consistency, removing all doubt even when it appears to
- * someone that the two other points are non-issues for that
- * particular descriptor type.

- * @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.

- * struct usb_request - describes one i/o request
- * @buf: Buffer used for data. Always provide this; some controllers
- * only use PIO, or don't use DMA for some endpoints.
- * @dma: DMA address corresponding to 'buf'. If you don't set this
- * field, and the usb controller needs one, it is responsible
- * for mapping and unmapping the buffer.
- * @length: Length of that data
- * @no_interrupt: If true, hints that no completion irq is needed.
- * Helpful sometimes with deep request queues that are handled
- * directly by DMA controllers.
- * @zero: If true, when writing data, makes the last packet be "short"
- * by adding a zero length packet as needed;
- * @short_not_ok: When reading data, makes short packets be
- * treated as errors (queue stops advancing till cleanup).
- * @complete: Function called when request completes, so this request and
- * its buffer may be re-used.
- * Reads terminate with a short packet, or when the buffer fills,
- * whichever comes first. When writes terminate, some data bytes
- * will usually still be in flight (often in a hardware fifo).
- * Errors (for reads or writes) stop the queue from advancing
- * until the completion function returns, so that any transfers
- * invalidated by the error may first be dequeued.
- * @context: For use by the completion callback
- * @list: For use by the gadget driver.
- * @status: Reports completion code, zero or a negative errno.
- * Normally, faults block the transfer queue from advancing until
- * the completion callback returns.
- * Code "-ESHUTDOWN" indicates completion caused by device disconnect,
- * or when the driver disabled the endpoint.
- * @actual: Reports bytes transferred to/from the buffer. For reads (OUT
- * transfers) this may be less than the requested length. If the
- * short_not_ok flag is set, short reads are treated as errors
- * even when status otherwise indicates successful completion.
- * Note that for writes (IN transfers) some data bytes may still
- * reside in a device-side FIFO when the request is reported as
- * complete.
- *
- * These are allocated/freed through the endpoint they're used with. The
- * hardware's driver can add extra per-request data to the memory it returns,
- * which often avoids separate memory allocations (potential failures),
- * later when the request is queued.
- *
- * Request flags affect request handling, such as whether a zero length
- * packet is written (the "zero" flag), whether a short read should be
- * treated as an error (blocking request queue advance, the "short_not_ok"
- * flag), or hinting that an interrupt is not required (the "no_interrupt"
- * flag, for use with deep request queues).
- *
- * Bulk endpoints can use any size buffers, and can also be used for interrupt
- * transfers. interrupt-only endpoints can be much less functional.
- *
- * NOTE: this is analagous to 'struct urb' on the host side, except that
- * it's thinner and promotes more pre-allocation.

- *
- * Each request is turned into one or more packets. The controller driver

- * Bulk endpoints can queue any amount of data; the transfer is packetized

- * protocols since not all usb hardware can successfully handle zero length
- * packets. (ZLPs may be explicitly written, and may be implicitly written if
- * the request 'zero' flag is set.) Bulk endpoints may also be used
- * for interrupt transfers; but the reverse is not true, and some endpoints
- * won't support every interrupt transfer. (Such as 768 byte packets.)
- *
- * Interrupt-only endpoints are less functional than bulk endpoints, for
- * example by not supporting queueing or not handling buffers that are
- * larger than the endpoint's maxpacket size. They may also treat data
- * toggle differently.
- *
- * Control endpoints ... after getting a setup() callback, the driver queues
- * one response (even if it would be zero length). That enables the

- * (Note that some USB device controllers disallow protocol stall responses
- * in some cases.) When control responses are deferred (the response is

- * endpoint addressing is only one of several hardware characteristics that
- * are in descriptors the ep0 implementation returns from setup() calls.

- * run on top of different usb controllers. It'll use endpoints set up by

- * The usb controller driver handles a few standard usb requests. Those
- * include set_address, and feature flags for devices, interfaces, and
- * endpoints (the get_status, set_feature, and clear_feature requests).
- *
- * Accordingly, the driver's setup() callback must always implement all

- * endpoints should be activated or (config 0) shut down.
- *
- * (Note that only the default control endpoint is supported. Neither

- * Most devices will ignore USB suspend/resume operations, and so will
