+   Basic firmware description. This will remain with
+   the driver for documentation purposes.
+
+   This represents an I2C firmware file encoded as a
+   string of unsigned char. Format is as follows:
+
+   char[0  ]=len0_MSB  -> len = len_MSB * 256 + len_LSB
+   char[1  ]=len0_LSB  -> length of first write transaction
+   char[2  ]=data0 -> first byte to be sent
+   char[3  ]=data1
+   char[4  ]=data2
+   char[   ]=...
+   char[M  ]=dataN  -> last byte to be sent
+   char[M+1]=len1_MSB  -> len = len_MSB * 256 + len_LSB
+   char[M+2]=len1_LSB  -> length of second write transaction
+   char[M+3]=data0
+   char[M+4]=data1
+   ...
+   etc.
+
+   The [len] value should be interpreted as follows:
+
+   len= len_MSB _ len_LSB
+   len=1111_1111_1111_1111   : End of I2C_SEQUENCE
+   len=0000_0000_0000_0000   : Reset command: Do hardware reset
+   len=0NNN_NNNN_NNNN_NNNN   : Normal transaction: number of bytes = {1:32767)
+   len=1WWW_WWWW_WWWW_WWWW   : Wait command: wait for {1:32767} ms
+
+   For the RESET and WAIT commands, the two following bytes will contain
+   immediately the length of the following transaction.

- *  Frequency control is done digitally -- ie out(port,encodefreq(95.8));

-/* The frame & image buffer mess.
-
-   Yes, this is a mess. Well, it used to be simple, but alas...  In this
-   module, 3 buffers schemes are used to get the data from the USB bus to
-   the user program. The first scheme involves the ISO buffers (called thus
-   since they transport ISO data from the USB controller), and not really
-   interesting. Suffices to say the data from this buffer is quickly
-   gathered in an interrupt handler (pwc_isoc_handler) and placed into the
-   frame buffer.
-
-   The frame buffer is the second scheme, and is the central element here.
-   It collects the data from a single frame from the camera (hence, the
-   name). Frames are delimited by the USB camera with a short USB packet,
-   so that's easy to detect. The frame buffers form a list that is filled
-   by the camera+USB controller and drained by the user process through
-   either read() or mmap().
-
-   The image buffer is the third scheme, in which frames are decompressed
-   and converted into planar format. For mmap() there is more than
-   one image buffer available.
-
-   The frame buffers provide the image buffering. In case the user process
-   is a bit slow, this introduces lag and some undesired side-effects.
-   The problem arises when the frame buffer is full. I used to drop the last
-   frame, which makes the data in the queue stale very quickly. But dropping
-   the frame at the head of the queue proved to be a litte bit more difficult.
-   I tried a circular linked scheme, but this introduced more problems than
-   it solved.
-
-   Because filling and draining are completely asynchronous processes, this
-   requires some fiddling with pointers and mutexes.
-
-   Eventually, I came up with a system with 2 lists: an 'empty' frame list
-   and a 'full' frame list:
-     * Initially, all frame buffers but one are on the 'empty' list; the one
-       remaining buffer is our initial fill frame.
-     * If a frame is needed for filling, we try to take it from the 'empty'
-       list, unless that list is empty, in which case we take the buffer at
-       the head of the 'full' list.
-     * When our fill buffer has been filled, it is appended to the 'full'
-       list.
-     * If a frame is needed by read() or mmap(), it is taken from the head of
-       the 'full' list, handled, and then appended to the 'empty' list. If no
-       buffer is present on the 'full' list, we wait.
-   The advantage is that the buffer that is currently being decompressed/
-   converted, is on neither list, and thus not in our way (any other scheme
-   I tried had the problem of old data lingering in the queue).
-
-   Whatever strategy you choose, it always remains a tradeoff: with more
-   frame buffers the chances of a missed frame are reduced. On the other
-   hand, on slower machines it introduces lag because the queue will
-   always be full.
