+ * hardware or revert them. When applying changes, all controls marked as
+ * dirty will be modified in the UVC device, and the dirty flag will be

+ * Video buffers queue management.
+ *
+ * Video queues is initialized by uvc_queue_init(). The function performs
+ * basic initialization of the uvc_video_queue struct and never fails.
+ *
+ * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
+ * uvc_free_buffers respectively. The former acquires the video queue lock,
+ * while the later must be called with the lock held (so that allocation can
+ * free previously allocated buffers). Trying to free buffers that are mapped
+ * to user space will return -EBUSY.
+ *
+ * Video buffers are managed using two queues. However, unlike most USB video
+ * drivers which use an in queue and an out queue, we use a main queue which
+ * holds all queued buffers (both 'empty' and 'done' buffers), and an irq
+ * queue which holds empty buffers. This design (copied from video-buf)
+ * minimizes locking in interrupt, as only one queue is shared between
+ * interrupt and user contexts.
+ *
+ * Use cases
+ * ---------
+ *
+ * Unless stated otherwise, all operations which modify the irq buffers queue
+ * are protected by the irq spinlock.
+ *
+ * 1. The user queues the buffers, starts streaming and dequeues a buffer.
+ *
+ * The buffers are added to the main and irq queues. Both operations are
+ * protected by the queue lock, and the latert is protected by the irq
+ * spinlock as well.
+ *
+ * The completion handler fetches a buffer from the irq queue and fills it
+ * with video data. If no buffer is available (irq queue empty), the handler
+ * returns immediately.
+ *
+ * When the buffer is full, the completion handler removes it from the irq
+ * queue, marks it as ready (UVC_BUF_STATE_DONE) and wake its wait queue.
+ * At that point, any process waiting on the buffer will be woken up. If a
+ * process tries to dequeue a buffer after it has been marked ready, the
+ * dequeing will succeed immediately.
+ *
+ * 2. Buffers are queued, user is waiting on a buffer and the device gets
+ * disconnected.
+ *
+ * When the device is disconnected, the kernel calls the completion handler
+ * with an appropriate status code. The handler marks all buffers in the
+ * irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
+ * that any process waiting on a buffer gets woken up.
+ *
+ * Waking up up the first buffer on the irq list is not enough, as the
+ * process waiting on the buffer might restart the dequeue operation
+ * immediately.

- * 22-Jul-2004 BJD Finished off device rewrite
- *
- * 21-Jul-2004 BJD Thanks to <herbet@13thfloor.at> for pointing out
- * problems with baud rate and loss of IR settings. Update
- * to add configuration via platform_device structure
- *
- * 28-Sep-2004 BJD Re-write for the following items
- * - S3C2410 and S3C2440 serial support
- * - Power Management support
- * - Fix console via IrDA devices
- * - SysReq (Herbert Pötzl)
- * - Break character handling (Herbert Pötzl)
- * - spin-lock initialisation (Dimitry Andric)
- * - added clock control
- * - updated init code to use platform_device info
- *
- * 06-Mar-2005 BJD Add s3c2440 fclk clock source
- *
- * 09-Mar-2005 BJD Add s3c2400 support
- *
- * 10-Mar-2005 LCVR Changed S3C2410_VA_UART to S3C24XX_VA_UART

-/* Note on 2440 fclk clock source handling
- *
- * Whilst it is possible to use the fclk as clock source, the method
- * of properly switching too/from this is currently un-implemented, so
- * whichever way is configured at startup is the one that will be used.
-*/
-
-/* Hote on 2410 error handling
- *
- * The s3c2410 manual has a love/hate affair with the contents of the
- * UERSTAT register in the UART blocks, and keeps marking some of the
- * error bits as reserved. Having checked with the s3c2410x01,
- * it copes with BREAKs properly, so I am happy to ignore the RESERVED
- * feature from the latter versions of the manual.
- *
- * If it becomes aparrent that latter versions of the 2410 remove these
- * bits, then action will have to be taken to differentiate the versions
- * and change the policy on BREAK
