- * ki_retry - iocb forward progress callback
- * @kiocb: The kiocb struct to advance by performing an operation.
- *
- * This callback is called when the AIO core wants a given AIO operation
- * to make forward progress. The kiocb argument describes the operation
- * that is to be performed. As the operation proceeds, perhaps partially,
- * ki_retry is expected to update the kiocb with progress made. Typically
- * ki_retry is set in the AIO core and it itself calls file_operations
- * helpers.
- *
- * ki_retry's return value determines when the AIO operation is completed
- * and an event is generated in the AIO event ring. Except the special
- * return values described below, the value that is returned from ki_retry
- * is transferred directly into the completion ring as the operation's
- * resulting status. Once this has happened ki_retry *MUST NOT* reference
- * the kiocb pointer again.
- *
- * If ki_retry returns -EIOCBQUEUED it has made a promise that aio_complete()
- * will be called on the kiocb pointer in the future. The AIO core will
- * not ask the method again -- ki_retry must ensure forward progress.
- * aio_complete() must be called once and only once in the future, multiple
- * calls may result in undefined behaviour.
- *
- * If ki_retry returns -EIOCBRETRY it has made a promise that kick_iocb()
- * will be called on the kiocb pointer in the future. This may happen
- * through generic helpers that associate kiocb->ki_wait with a wait
- * queue head that ki_retry uses via current->io_wait. It can also happen
- * with custom tracking and manual calls to kick_iocb(), though that is
- * discouraged. In either case, kick_iocb() must be called once and only
- * once. ki_retry must ensure forward progress, the AIO core will wait
- * indefinitely for kick_iocb() to be called.

+ IORESOURCE_IRQ_HIGHLEVEL;
+ platform_device_register(&brcmfmac_device);
+}
+ *
+ *
+ * Note: the brcmfmac can be loaded as module or be statically built-in into
+ * the kernel. If built-in then do note that it uses module_init (and
+ * module_exit) routines which equal device_initcall. So if you intend to
+ * create a module with the platform specific data for the brcmfmac and have
+ * it built-in to the kernel then use a higher initcall then device_initcall
+ * (see init.h). If this is not done then brcmfmac will load without problems
+ * but will not pickup the platform data.
+ *
+ * When the driver does not "detect" platform driver data then it will continue
+ * without reporting anything and just assume there is no data needed. Which is
+ * probably true for most platforms.
+ *
+ * Explanation of the platform_data fields:
+ *
+ * drive_strength: is the preferred drive_strength to be used for the SDIO
+ * pins. If 0 then a default value will be used. This is the target drive
+ * strength, the exact drive strength which will be used depends on the
+ * capabilities of the device.
+ *
+ * oob_irq_supported: does the board have support for OOB interrupts. SDIO
+ * in-band interrupts are relatively slow and for having less overhead on
+ * interrupt processing an out of band interrupt can be used. If the HW
+ * supports this then enable this by setting this field to true and configure
+ * the oob related fields.
+ *
+ * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
+ * used for registering the irq using request_irq function.
+ *
+ * power_on: This function is called by the brcmfmac when the module gets
+ * loaded. This can be particularly useful for low power devices. The platform
+ * spcific routine may for example decide to power up the complete device.
+ * If there is no use-case for this function then provide NULL.
+ *
+ * power_off: This function is called by the brcmfmac when the module gets
+ * unloaded. At this point the device can be powered down or otherwise be reset.
+ * So if an actual power_off is not supported but reset is then reset the device
+ * when this function gets called. This can be particularly useful for low power
+ * devices. If there is no use-case for this function (either power-down or
+ * reset) then provide NULL.
+ *
+ * reset: This function can get called if the device communication broke down.
+ * This functionality is particularly useful in case of SDIO type devices. It is
+ * possible to reset a dongle via sdio data interface, but it requires that
+ * this is fully functional. This function is chip/module specific and this
+ * function should return only after the complete reset has completed.

+ * hci_conn_get() and hci_conn_put() are used to control the life-time of an
+ * "hci_conn" object. They do not guarantee that the hci_conn object is running,
+ * working or anything else. They just guarantee that the object is available
+ * and can be dereferenced. So you can use its locks, local variables and any
+ * other constant data.
+ * Before accessing runtime data, you _must_ lock the object and then check that
+ * it is still running. As soon as you release the locks, the connection might
+ * get dropped, though.
+ *
+ * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control
+ * how long the underlying connection is held. So every channel that runs on the
+ * hci_conn object calls this to prevent the connection from disappearing. As
+ * long as you hold a device, you must also guarantee that you have a valid
+ * reference to the device via hci_conn_get() (or the initial reference from
+ * hci_conn_add()).
+ * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't
+ * break because nobody cares for that. But this means, we cannot use
+ * _get()/_drop() in it, but require the caller to have a valid ref (FIXME).
