Our old start of frame detection code wrongly assumes that the sof
marker always lives at the beginning of the frame. At least for the
0c45:602a camera this is not the case. This patch also improves
the framerate from 28 fps to 30 fps with the 0c45:6005 and 0c45:6007

I've a 0c45:6007 camera and it works fine with the gspca_sonixb driver,
so make that handle it instead of the deprecated sn9c102 driver.

Support for mt9m001 (mi1300) is broken:
- Table is incomplete;
- Only one resolution is currently supported by the driver;
- Resolution is incomplete;
- it complains about broken JPEG headers.
Use the same init found on em28xx driver, and properly report the
output format as 8-bits GRAY.

Changeset 35680ba broke several devices:
- Sony Playstation Eye (1415:2000);
- Gigaware model 25-234 (0c45:628f);
- Logitech Messenger Plus (046d:08f6).
Probably more devices were broken by this change.
What happens is that several devices don't need to save some bandwidth
for audio.
Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since
it will reduce the alt number twice, on devices with audio.
So, let's just revert the broken logic, and think on a better solution
for usb 1.1 devices with audio that can't use the maximum packetsize.

I found that the problems people have reported with the USB-TV-stick
"Terratec Cinergy Hybrid T USB XS" (USB-ID: 0ccd:0042)
are coming from a wrong header file in the v4l-sources.
Attached is a diff, which fixes the problem (tested successfully here).
Obviously the USB-ID has been associated with a wrong chip: EM2880
instead of EM2882, which would be correct.

The RC5 old decoder used custom_irq to indicate the need of handling
the IRQ on a different way. Instead of doing it, let the core just call the
bttv input IRQ handler, and add the code there to call the legacy decoder.
While here, remove the gpioq waitqueue, as this is not used anywhere, and
add a debug msg to help removing the legacy RC5 code.

I've got code which adds support of GoTView PCI DVD3 Hybrid tuner in
cx18 module and Andy Walls in ivtv mailing-list gave me some advice on
making a patch and sending it here. So here's the patch against
staging/2.6.37-rc1 branch (the tutorial recommends to include it as
plain text but if it's the case I can surely send as an attachment):
Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.

that the v4l1 compat code is removed from the pwc driver there is no reason

The struct that describes a rc mapping had an weird and long name.
We should properly name it, to make easier for developers to work
with it, and to avoid confusion.
Basically, generated by this script:
for i in `find drivers/staging -type f -name *.[ch]` `find include/media -type f -name *.[ch]` `find drivers/media -type f -name *.[ch]`; do sed s,ir_scancode_table,rc_map,g <$i >a && mv a $i; done

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
- ir-core.h to rc-core.h
- IR_CORE to RC_CORE
- namespace inside rc-core.c/rc-core.h

Now, just one old bttv board uses the old RC5 raw decoding routines.
Its conversion to rc-core requires the generation of IRQ data for both
positive and negative transitions at the IRQ line. I'm not sure if
bttv driver supports it or if the transitions will be reliable enough.
So, due to the lack of hardware for testing, the better for now is to
just move the legacy routines to bttv driver, and wait for someone with
a Nebula Digi could help to port it to use also rc-core raw decoders.
