The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on
i2c_get_adapdata to return the v4l2_device. However, this is not always
possible on embedded platforms. So modify the API to pass the v4l2_device
pointer explicitly.Signed-off-by: Hans Verkuil

Now that all drivers are converted to v4l2_subdev we can remove legacy code
in v4l2-common. Also move the documentation of the internal API to
v4l2-subdev.h where it really belongs.Signed-off-by: Hans Verkuil

If usb_interface.dev is used as dev parameter for v4l2_device_register
v4l2_dev.name contains the v4l driver/module name and usb device and
interface instead of a simple "usb x-y".
It also matches the recommendation to set the parent devices for usb
drivers.Signed-off-by: Janne Grunau

The DMA transfers in pxa_camera showed some weaknesses in
multiple queued buffers context :
- poll/select problem
The bug shows up with capture_example tool from v4l2 hg
tree. The process just "stalls" on a "select timeout".- multiple buffers DMA starting
When multiple buffers were queued, the DMA channels were
always started right away. This is not optimal, as a
special case appears when the first EOF was not yet
reached, and the DMA channels were prematurely started.- Maintainability
DMA code was a bit obfuscated. Rationalize the code to be
easily maintainable by anyone.- DMA hot chaining
DMA is not stopped anymore to queue a buffer, the buffer
is queued with DMA running. As a tribute, a corner case
exists where chaining happens while DMA finishes the
chain, and the capture is restarted to deal with the
missed link buffer.This patch attemps to address these issues / improvements.

Add support for ProVideo PV-183 to bttv
This patch adds support for the ProVideo PV-183 card to the bttv
device driver. The PV-183 is a PCI card with 8 BT878 devices plus a Hint
Corp HiNT HB4 PCI-PCI Bridge. Each BT878 has two composite input channels
available. There are no tuners on this card.Signed-off-by: Alan McIvor

Normally the parent device of v4l2_device is used as the video device
node's parent. But if it was not set, then use the parent field in the
video_device struct.This is needed in the cx88 driver, which has one core v4l2_device but
creates multiple pci devices (one each for raw and mpeg video).So you cannot associate the core v4l2_device with a particular PCI device,
but you can do that for each video_device.Signed-off-by: Hans Verkuil

The lock_norm module parameter doesn't look terribly useful. If you

I have a GeoVision GV-800(S) card, it has 4 CONEXANT BT878A chips.
It has 16 video inputs and 4 audio inputs, and it is almost identical
to the GV-800, as seen on http://bttv-gallery.de .
The only difference appears to be the analog mux, it has a CD22M3494
in place of the MT8816AP. The card has a blue PCB, as seen in this
picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg .This card wasn't originally supported, and it was detected as
UNKNOWN/GENERIC. The video inputs weren't working, so I tried
"forcing" a few cards like the GeoVision GV-600, but there was still
no video. So I made a patch to support this card, based on the Kodicom
4400r.The GV-800(S) is identified as follows:

Capabilities: [4c] Power Management version 2As you can see, the GV-800(S) card is almost identical to the GV-800
on bttv-gallery, so this patch might also work for that card. If not,
only a few changes should be required on the gv800s_write() function.After this patch, the video inputs work correctly on linux 2.6.24 and
2.6.27 using the software 'motion'. The input order may seem a little
odd, but it's the order the original software/driver uses, and I decided
to keep that order to get the most out of the card.I tried to get the audio working with the snd-bt87x module, but I only
get noise from every audio input, even after selecting a different mux
with alsamixer. Also, after trying to play sound from those sources, I
randomly get a RISC error about an invalid RISC opcode, and then that
output stops working. I also can't change the sampling rate when
recording. Any pointers to adding audio support are welcome.Signed-off-by: Bruno Christo
