I have a Cisco VT Camera, and it was just collecting dust. I decided to
try connecting it to my Linux box at home.
Just a disgression about the product. The Cisco VT Camera is a webcam
Cisco sold to work with their IP phone hardware and software. It's mostly
useless on Windows, as it interfaces only to Cisco software. You can find
some for cheap on eBay...
Physically, it's just a Logitech Pro 4000. The only difference with the
Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe
Cisco is now selling the Cisco VT Camera II, which look to be something
else...
So, assuming that it was a Pro 4000 inside, I created the little patch
attached.
I'm new to webcam under Linux, but I managed to get an image from it using
xawtv, and the image looked all right, so I consider that a success. The
imaged seemed a bit small and I could not get the microphone driver loaded,
but I assume it's my lack of experience. Note that I did not try any other
type_id, but this one works great.

The dvb-pll sleep function could only send a 2-byte sequence to the PLL.
This isn't enough in some cases, for example fmd1216me will need to send
a 4-byte command to set both BB and AB to the correct values.
Instead of using a fake band with a frequency of 0 to store the sleep
data (which has room for only two bytes), the new sleep function works
like the init function. A new pointer is added to the pll description,
and when non-NULL points to a buffer with the length and data to send.

The IF frequency was specified for each band, but it's not something that
changes from band to band. None of the tuner definitions had a different
IF frequency (called offset) from one band to another.

Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer. Some didn't and so
would always be rounded down.
This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged. PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.
In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution. One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.
PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step
Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset. Rather than adding stepsize/2, it was adding a full
stepsize. The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2. The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

Change a 00 to just 0
Detect zero-length I2C messages and return not supported. I think I know
how to send one, but the problem is getting the slave's ack. The only
point of a zero-length message is for probing; too see if the slave will
ack its address. Since we don't know how to get the ack, we can't
support zero-length messages in a useful way, so it's probably best to
just return not supported for them.

Write some better documentation about what might be known about how the
m920x I2C works, since a datasheet is lacking.
The I2C xfer function should now handle more types of I2C transactions
than it could before. Those it can't, will return error codes instead of
being executed incorrectly. Multi-byte reads were not being done
correctly, which should be fixed.

Once the devices have been registered anyone can start changing the inputs or
TV standard before they have been initialized by the driver. This leads to
cases were the input is changed in an udev rule, but after that rule is
triggered the tail-end of the ivtv driver initialization can override
that by selecting the tuner input.
The correct sequence is to first setup the input, initial frequency and TV
standard before finally registering the video devices. This prevents any
udev rules from being triggered prematurely.
