| 43 | /** | ||
| 44 | * struct usb_function - describes one function of a configuration | ||
| 45 | * @name: For diagnostics, identifies the function. | ||
| 46 | * @strings: tables of strings, keyed by identifiers assigned during bind() | ||
| 47 | * and by language IDs provided in control requests | ||
| 48 | * @descriptors: Table of full (or low) speed descriptors, using interface and | ||
| 49 | * string identifiers assigned during @bind(). If this pointer is null, | ||
| 50 | * the function will not be available at full speed (or at low speed). | ||
| 51 | * @hs_descriptors: Table of high speed descriptors, using interface and | ||
| 52 | * string identifiers assigned during @bind(). If this pointer is null, | ||
| 53 | * the function will not be available at high speed. | ||
| 54 | * @config: assigned when @usb_add_function() is called; this is the | ||
| 55 | * configuration with which this function is associated. | ||
| 56 | * @bind: Before the gadget can register, all of its functions bind() to the | ||
| 57 | * available resources including string and interface identifiers used | ||
| 58 | * in interface or class descriptors; endpoints; I/O buffers; and so on. | ||
| 59 | * @unbind: Reverses @bind; called as a side effect of unregistering the | ||
| 60 | * driver which added this function. | ||
| 61 | * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may | ||
| 62 | * initialize usb_ep.driver data at this time (when it is used). | ||
| 63 | * Note that setting an interface to its current altsetting resets | ||
| 64 | * interface state, and that all interfaces have a disabled state. | ||
| 65 | * @get_alt: Returns the active altsetting. If this is not provided, | ||
| 66 | * then only altsetting zero is supported. | ||
| 67 | * @disable: (REQUIRED) Indicates the function should be disabled. Reasons | ||
| 68 | * include host resetting or reconfiguring the gadget, and disconnection. | ||
| 69 | * @setup: Used for interface-specific control requests. | ||
| 70 | * @suspend: Notifies functions when the host stops sending USB traffic. | ||
| 71 | * @resume: Notifies functions when the host restarts USB traffic. | ||
| 72 | * | ||
| 73 | * A single USB function uses one or more interfaces, and should in most | ||
| 74 | * cases support operation at both full and high speeds. Each function is | ||
| 75 | * associated by @usb_add_function() with a one configuration; that function | ||
| 76 | * causes @bind() to be called so resources can be allocated as part of | ||
| 77 | * setting up a gadget driver. Those resources include endpoints, which | ||
| 78 | * should be allocated using @usb_ep_autoconfig(). | ||
| 79 | * | ||
| 80 | * To support dual speed operation, a function driver provides descriptors | ||
| 81 | * for both high and full speed operation. Except in rare cases that don't | ||
| 82 | * involve bulk endpoints, each speed needs different endpoint descriptors. | ||
| 83 | * | ||
| 84 | * Function drivers choose their own strategies for managing instance data. | ||
| 85 | * The simplest strategy just declares it "static', which means the function | ||
| 86 | * can only be activated once. If the function needs to be exposed in more | ||
| 87 | * than one configuration at a given speed, it needs to support multiple | ||
| 88 | * usb_function structures (one for each configuration). | ||
| 89 | * | ||
| 90 | * A more complex strategy might encapsulate a @usb_function structure inside | ||
| 91 | * a driver-specific instance structure to allows multiple activations. An | ||
| 92 | * example of multiple activations might be a CDC ACM function that supports | ||
| 93 | * two or more distinct instances within the same configuration, providing | ||
| 94 | * several independent logical data links to a USB host. | ||

| 284 | * OPEN ISSUE: it appears that some WUSB devices will need to be | ||
| 285 | * built by combining a normal (wired) gadget with a wireless one. | ||
| 286 | * This revision of the gadget framework should probably try to make | ||
| 287 | * sure doing that won't hurt too much. | ||
| 288 | * | ||
| 289 | * One notion for how to handle Wireless USB devices involves: | ||
| 290 | * (a) a second gadget here, discovery mechanism TBD, but likely | ||
| 291 | * needing separate "register/unregister WUSB gadget" calls; | ||
| 292 | * (b) updates to usb_gadget to include flags "is it wireless", | ||
| 293 | * "is it wired", plus (presumably in a wrapper structure) | ||
| 294 | * bandgroup and PHY info; | ||
| 295 | * (c) presumably a wireless_ep wrapping a usb_ep, and reporting | ||
| 296 | * wireless-specific parameters like maxburst and maxsequence; | ||
| 297 | * (d) configurations that are specific to wireless links; | ||
| 298 | * (e) function drivers that understand wireless configs and will | ||
| 299 | * support wireless for (additional) function instances; | ||
| 300 | * (f) a function to support association setup (like CBAF), not | ||
| 301 | * necessarily requiring a wireless adapter; | ||
| 302 | * (g) composite device setup that can create one or more wireless | ||
| 303 | * configs, including appropriate association setup support; | ||
| 304 | * (h) more, TBD. | ||
