-/* Should ease the (re-)usage of drivers supporting cards with (different)
- video codecs. The codecs register to this module their functionality,
- and the processors (masters) can attach to them if they fit.
-
- The codecs are typically have a "strong" binding to their master - so I
- don't think it makes sense to have a full blown interfacing as with e.g.
- i2c. If you have an other opinion, let's discuss & implement it :-)))
-
- Usage:
-
- The slave has just to setup the videocodec structure and use two functions:
- videocodec_register(codecdata);
- videocodec_unregister(codecdata);
- The best is just calling them at module (de-)initialisation.
-
- The master sets up the structure videocodec_master and calls:
- codecdata=videocodec_attach(master_codecdata);
- videocodec_detach(codecdata);
-
- The slave is called during attach/detach via functions setup previously
- during register. At that time, the master_data pointer is set up
- and the slave can access any io registers of the master device (in the case
- the slave is bound to it). Otherwise it doesn't need this functions and
- therfor they may not be initialized.
-
- The other functions are just for convenience, as they are for sure used by
- most/all of the codecs. The last ones may be omitted, too.
-
- See the structure declaration below for more information and which data has
- to be set up for the master and the slave.
-
- ----------------------------------------------------------------------------
- The master should have "knowledge" of the slave and vice versa. So the data
- structures sent to/from slave via set_data/get_data set_image/get_image are
- device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

-
-/*
- ==== master setup ====
- name -> name of the device structure for reference and debugging
- master_data -> data ref. for the master (e.g. the zr36055,57,67)
- readreg -> ref. to read-fn from register (setup by master, used by slave)
- writereg -> ref. to write-fn to register (setup by master, used by slave)
- this two functions do the lowlevel I/O job
-
- ==== slave functionality setup ====
- slave_data -> data ref. for the slave (e.g. the zr36050,60)
- check -> fn-ref. checks availability of an device, returns -EIO on failure or
- the type on success
- this makes espcecially sense if a driver module supports more than
- one codec which may be quite similar to access, nevertheless it
- is good for a first functionality check
-
- -- main functions you always need for compression/decompression --
-
- set_mode -> this fn-ref. resets the entire codec, and sets up the mode
- with the last defined norm/size (or device default if not
- available) - it returns 0 if the mode is possible
- set_size -> this fn-ref. sets the norm and image size for
- compression/decompression (returns 0 on success)
- the norm param is defined in videodev2.h (V4L2_STD_*)
-
- additional setup may be available, too - but the codec should work with
- some default values even without this
-
- set_data -> sets device-specific data (tables, quality etc.)
- get_data -> query device-specific data (tables, quality etc.)
-
- if the device delivers interrupts, they may be setup/handled here
- setup_interrupt -> codec irq setup (not needed for 36050/60)
- handle_interrupt -> codec irq handling (not needed for 36050/60)
-
- if the device delivers pictures, they may be handled here
- put_image -> puts image data to the codec (not needed for 36050/60)
- get_image -> gets image data from the codec (not needed for 36050/60)
- the calls include frame numbers and flags (even/odd/...)
- if needed and a flag which allows blocking until its ready

-/*
- Currently there is only a information display planned, as the layer
- is not visible for the user space at all.
-
- Information is available via procfs. The current entry is "/proc/videocodecs"
- but it makes sense to "hide" it in the /proc/video tree of v4l(2) --TODO--.

- * Allocate the MJPEG grab buffers.

- * I could never check it because I have a zr36067)
- *
- * RJ: The contents grab buffers needs never be accessed in the driver.
- * Therefore there is no need to allocate them with vmalloc in order
- * to get a contiguous virtual memory space.
- * I don't understand why many other drivers first allocate them with
- * vmalloc (which uses internally also get_zeroed_page, but delivers you
- * virtual addresses) and then again have to make a lot of efforts
- * to get the physical address.
- *
- * Ben Capper:
- * On big-endian architectures (such as ppc) some extra steps
- * are needed. When reading and writing to the stat_com array
- * and fragment buffers, the device expects to see little-
- * endian values. The use of cpu_to_le32() and le32_to_cpu()
- * in this function (and one or two others in zoran_device.c)
- * ensure that these values are always stored in little-endian
- * form, regardless of architecture. The zr36057 does Very Bad
- * Things on big endian architectures if the stat_com array
- * and fragment buffers are not little-endian.
