The cx231xx_set_Colibri_For_LowIF() function is only ever called if the tuner has a DIF (see vidioc_s_frequency() in cx231xx-video.c). Hence, we do not need to do a board specific check in this function. Signed-off-by:

The current code was deciding whether a DIF was present based on the board profile. However, this is just another thing for someone to get wrong when adding new boards. Make the decision based on the tuner instead, so that a developer adding new boards only needs to specify which tuner the device has. Of course, the first time somebody adds a board with a tuner other than xc5000 or tda18271, he/she will need to add another line for that tuner. But we provide a friendly message in dmesg to let them know that. Signed-off-by:

Nobody is ever going to implement an i2c based IR controller on a bridge that has an onboard universal IR receiver. This stuff was all copied from em28xx, which has old enough versions of the chip that some didn't have onboard IR. Remove the stubs related to i2c based IR (keeping the cx231xx-input code).

The video grabber reference design (Veyron) does not have a tuner input, so do not have it defined in the board profile. Signed-off-by:

Extend the board profile structure to allow configuration of the output mode. Right now they are all doing VIP 1.1 format, but we have a board that needs ITU656 format (which hasn't been checked in yet). Signed-off-by:

Add initial support for the Hauppauge USBLive 2 (2040:c200). Note that I had to copy a bunch of the case statements used for the Conexant video grabber reference design (which also doesn't have a tuner). This will likely need to be refactored out into the board profile. Signed-off-by:

The tuner is on i2c port 3 just like all the reference designs. Having it improperly set to port #1 causes the tuner initialization to fail when enabling the device. Signed-off-by:

If switching to a tuner input, reset the standard and tune to the last known frequency. We need to do this in particular for this bridge since the tuner gets powered down when captuing on the composite or s-video inputs. Signed-off-by:

Remove a hack which was jammed into s_input to force the device into bulk mode at runtime (an abuse of the API). If this sort of functionality is actually needed (aside from the existing "transfer_mode" modprobe variable), a patch can be submitted which makes use of a private control. Signed-off-by:

The Exeter hardware design does not use GPIOs to manage whether its in digital mode or analog mode, but we need to setup the power control properly. For that board, setup power control and remove the mux select call. It is highly likely that this change could be used by other boards as well, which would make power management cleaner (fixing known issues transitioning between analog and digital mode). Signed-off-by:

You cannot call the video_mux routine from within the isoc setup, because that code is shared with the digital isoc handler. This was causing the GPIOs and power control to be put into the wrong state when starting up digital mode. Signed-off-by:

We need to clear out the field before setting individual bits, or else we end up with a union of whatever was there and what we are trying to set. For example, switching to digital mode ends up being 0x30 instead of 0x10 if we were previously in analog tv mode. Signed-off-by:

Move the responsibility for setting up the horizontal and vertical scalers entirely to the cx25840 driver. The cx231xx-avcore was actually programming garbage into the HSCALE_CTRL and VSCALE_CTRL registers (because of differences in how the em28xx driver worked, which the cx231xx driver was derived from). The net effect is that the scaler now works properly (tested with both PAL and NTSC under mplayer and tvtime). This patch also gets rid of cx25840 errors showing up in dmesg which say "720x480 is not a valid size" (since we now properly setup the size of the active video area). Signed-off-by:

There is no need for a switch statement here. Use the contents of the board profile to dictate the tuner driver and i2c address. Eventually if a board ever comes around which has a different i2c bus than #1, well that should be a field in the board profile as well. Signed-off-by:

The current code was sending one videobuf per field (despite having specified V4L2_FIELD_SEQ_TB during setup). As a result, application which used the read() interface would work, except they would sometimes have the fields reversed (depending on the luck of which field the device was on when the application started VBI capture). The net effect was that CC decoding would only work about 50% of the time. Restructure the VBI code a bit so that works like all the other drivers, such that both fields are delivered in a single videobuf buffer, which ensures that they are always received in a predictable order.

Configure the tda18271 to use a smaller transaction size by default, which works around some sort of i2c bug in the Polaris driver (which needs to be debugged). This should be safe for other boards (being in tuner-core means it will be enabled by default), although testing needs to be done. Signed-off-by:

This patch, which basically reverts 6d77444a, fixes an occasional on-boot or on-capture hang on the XO-1 laptop. It seems like the cafe hardware is flakier than we thought and that in some cases, the commands get executed but are never reported as completed (even if we substantially increase the delays before reading registers). Reintroduce the 1-second CAFE_SMBUS_TIMEOUT to catch and avoid this strange hardware bug. Signed-off-by:

The go7007 driver has a potential buffer overflow and pointer corruption bug which causes a crash while capturing MJPEG. The motion detection (MODET) active_map array can be overflowed by JPEG frame data that emulates a MODET start code. The active_map overflow overwrites the active_buf pointer, causing a crash. The JPEG data that emulated MODET start code was being removed from the output, resulting in garbled JPEG frames. Therefore ignore MODET start codes when MODET is not enabled. Signed-off-by:

I added a code to the driver to force it to produce a warning. This were intended to remind me about a very bad hack. I never found a way to workaround. So, instead of those warnings: drivers/staging/tm6000/tm6000-core.c: In function ‘tm6000_init_analog_mode’: drivers/staging/tm6000/tm6000-core.c:328: warning: ISO C90 forbids mixed declarations and code Let's document the issue and hope if someone with the support of the vendor might fix it.
