saa7115 module is capable of calculating the proper FIR tables. However, there were 4 hardcoded tables for the standard resolution. Signed-off-by: -

Adjust temporal filter if necessary. The problem with the temporal filter is that it works well with full resolution capturing, but not when the capture window is scaled (the filter introduces a ghosting effect). So if the capture window changed, and there is no updated filter value, then the filter is set depending on whether the new window is full resolution or not. For full resolution a setting of 8 really improves the video quality, especially if the original video quality is suboptimal. Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.

Add a tuner config parameter for TDA9887, default_pll_gating_18, that changes the L standard PLL gating value from 36% to 0% (datasheet says 0%, tda9887 code says 18%). Turn this on for Microtune 4049FM5, as recomended by tuner datasheet. Signed-off-by:

The release callback was installed in ops.release, it should have been ops.release_sec. This prevented to front-end release from getting called. Signed-off-by:

Matthieu Castet found that with the rewritten dib3000mc-driver the PID-parsing was handled correctly. This changeset fixes it. Thanks Matthieu Signed-off-by:

There are several boards on V4L that can work with several different helper modules for audio/video encoding/decoding and similar stuff. This patch adds the capability of choicing between autoselecting the pertinent helper modules for each driver, or to manually selecting them. Acked-by:

Several audio/video encoders/decoders were just bound as if they were part of the core driver. In fact, they are generic enough to be used by other drivers as well, since they use I2C event bus to communicate. Signed-off-by: -

when checking the -Wextra signedness warnings issued by gcc 4.1 I came across this one: drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false Since videobuf_reqbufs() returns negative values on errors the current code does no real error checking since gcc removes the comparison. This patch fixes this issue by making ret a normal, signed integer. Signed-off-by:

Several changes at register stuff were done since commit b45009b0, but I've forgot to add the copyright line for this. Those changes allowed cx88 to have multiple tuners, allowing it to support hardware with separated radio and video tuners. It also allows binding a tuner to an specific i2c address. Signed-off-by:

cx88-alsa can be compiled in (in distro built kernels, for example), but not used. In those cases, the audio DMA restart is needed for proper sound on NICAM channels. This patch enables the DMA restart even with ALSA, but the functions now check if cx88-alsa is really active. Signed-off-by:

Apparently there are two types of knc1 dvb-s plus cards with different tuners (as for the knc1 dvb-s ones). This patch adds support for those cards with subsystem id 1894:0011. Successfully tested by: Benjamin Weber <benny1990@gmail.com> Signed-off-by:

If the FX2 does not reset properly during reboot, it can present an invalid USB device ID and fail to attach. Prevent this situation from occuring by resetting the USB part of the card when the PCI part probes. Also fix the GPIO configurations so that analog capture will not inadvertantly reset the USB part.
