1ebba670ed V4L/DVB (5497): Additional card support for bttv driver
SSAI (www.ssai.us) makes several Bt878-based capture cards that get used in our
surveillance, conferencing, and medical imaging systems.  The attached
relatively small patch adds support for these cards, which fall into two broad
* boards with one or more Bt878s, one or more composite inputs, and no S-video
  or tuner inputs
* boards with one Bt878, one composite input, one S-video input, and no tuner
  input

a63e157fc6 V4L/DVB (5461): Pwc: cisco VT Camera support
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.

d519dcf61e V4L/DVB (5457): Dvb-pll: Replace sleep function with a more capable one
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.

0fd17d6da8 V4L/DVB (5455): Dvb-pll: Adjust rounding to be consistent
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.

57f8dcf90b V4L/DVB (5428): M920x: Detect zero-length I2C messages and fix a typo
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.

d40860f8e2 V4L/DVB (5427): M920x: Improve I2C operations
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.
