The V4L2 API requires a unique bus_info string returned as part of the v4l2_capability structure. These changes gather up the USB address information, from the underlying device, into a string and report that out through v4l2 and via sysfs (for completeness). Signed-off-by:

sn9c102 is a v4l2 driver, except it used a couple v4l1 helper functions. Stop using those functions and depend on V4L2 in Kconfig. Acked-by:

Makes sure they don't get copied onto the stack. Signed-off-by:

There were many places in the driver which had long sequences of constant register initializations. These were done with one function call per register. The register address and value were immediate values in the function calls. This is very inefficient, as each register and value take twice the space when they are code, as each includes a push instruction to put it on the stack. There there is the overhead, both size and time, for a function call for each register. It's also quite a few lines of C code to do this. The patch creates a function that writes multiple registers from a list, and a macro that makes it easy to construct a such a list as a const static local to send to the function. This gets rid of quite a bit of C code, and shrinks the driver by around 8k, while at the same time being more efficient. Acked-by:

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 Signed-off-by:

When the tuner is attached, the tda10046 is not initilized yet, so it is searching for its firmware. If the tuner is attached to the tda10046 silent i2c port, a bus collision can occur. Now the version is probed during the first init or sleep call. Signed-off-by:

This patch causes the bttv driver to automatically load the dvb-bt8xx module for bttv/dvb hybrid cards. Successfully tested with a pcHDTV HD-2000 card. This patch is based on the recent patches to enable autoloading of cx88-dvb, cx88-blackbird and saa7134-dvb. Signed-off-by:

ATI HDTV Wonder needs to initialize some registers before allowing the tuner to start working. The current logic have lots of magic. This patch makes the code cleaner, using ARRAY_SIZE() for the initialization array and using a bidimensional array, instead of doing some stuff like: &buffer[i+2] Signed-off-by: -

there were several "magic" for loops, addressing gpiomux array size (4). Adrian Bunk showed that one of the loops were wrong, going from 0 to 4. This patch provides the right fix for this trouble, by using ARRAY_SIZE on all places where we have a for loop using gpiomux. Thanks to: Adrian Bunk <bunk@stusta.de> for pointing me about this trouble. Signed-off-by: -

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. Signed-off-by:

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. Acked-by:

Trent Piepho authored
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. Signed-off-by:

The attach code for HAUPPAUGE_HVR3000 and HAUPPAUGE_HVR1300 is exactly the same as the code used by HAUPPAUGE_HVR1100, HAUPPAUGE_HVR1100LP, and WINFAST_DTV2000H. So, those first two cards are added to the case block used by the last three. Signed-off-by:
