Kernel module (device driver) for dt3155 frame grabber
video4linux2 compliant (finally). Works with "xawtv -f".
======================================================
This driver is written (almost) from scratch, using the
allocator developed for dt3155pci see bellow). The driver
uses videobuf-dma-contig interface modified to use the above
mentioned allocator instead of dma_alloc_coheren().
The first thing to do was to design a new allocator based
on allocating a configurable number of 4MB chunks of memory,
that latter are broken into frame buffers of 768x576 bytes
kept in different FIFOs (queues). As far as the driver autoloads
as a kernel module during kernel boot, the allocation of 4MB
chunks succeeds.
The driver keeps three FIFOs: one for 4MB chunks, one for free
buffers (available for allocations) and one for buffers already
allocated. Allocation/deallocation is done automatically though
the video4linux videobuf subsystem (some pointers to functions
are replaced by driver supplied functions).
Sure, there are problems:
1. The device tested to work with "xawtv -f" either via read()
method (DT3155_STREAMING not selected), or via mmap() method
(DT3155_STREAMING is selected) only. This coresponds to either
cap->capabilities = V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_READWRITE;
or
cap->capabilities = V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_STREAMING;
but not when
cap->capabilities = V4L2_CAP_VIDEO_CAPTURE |
V4L2_CAP_STREAMING |
V4L2_CAP_READWRITE;
This is because xawtv calls poll() before starting streaming,
but videobuf_poll_stream() automatically starts reading if streaming
is not started.
This selection is made during kernel configuration (for now).
2. Works for CCIR, but should work for RS-170 (not tested)
This is made also during kernel configuration.
3. Could work for multiple dt3155 frame grabbers in a PC,
(private data is allocated during PCI probe() method), but
is not tested due to lack of a second board.
4. Not tested on a BIG ENDIAN architecture.
5. Many others you could find .... :-)
All critics, comments, suggestions are wellcome.

Don't redefine something that we already have in the core
kernel. Also move to use PCI_DEVICE() macros to make things
a bit simpler when changing the define.

If we're not associated, we should not send wireless events to let userspace
know that we just left an ESSID, simply because we havent yet joined it.
If we keep on doing that, wpa_supplicant could receive such events while
actually trying to join an ESSID, and thus decide to stop trying. This leads
to a lot of connection failures as this driver seems to be sending GIWAP
events quite a lot.
