This adds a struct v4l2_device to the go7007 device struct and registers it during v4l2 initialization. The v4l2_device registration overwrites the go->dev device_data, which is a struct usb_interface with intfdata set to the struct go7007. This changes intfdata to point to the struct v4l2_device inside struct go7007, which is what v4l2_device_register will also set it to (and warn about non-null drvdata on register.) Since usb disconnect can happen any time, this intfdata should always be present. Signed-off-by:

Avoid legacy IR I2C probing for PVR-150, PVR-500, and PVR-350 cards. This still probes, but restricts the possbile addresses probed per card. Also removed legacy probe addresses for the KNC and PixelView cards which are not supported by ivtv as far as I know. Signed-off-by:

This change creates per cx18 instances of IR_i2c_init_data for handing over initialization data to ir-kbd-i2c, since that module wants non-const data even though it never modifies the data. Signed-off-by:

Add explicit support for the AVerTV M116 for use with the ir-kbd-i2c module. This also eases future support for other AVerMedia ivtv boards with the same microcontroller program at I2C address 0x40. This is a reworked version of an earlier patch that was... Reviewed-by:

This avoids collisions of legacy IR controller probing with known I2C devices in the card definitions in ivtv-cards.c. I2C driver modules for device listed explicitly in a card definition should always take precedence over a probe guessing where and IR controller may be. Reviewed-by:

Add a module parameter to adjust I2C SCL clock period per board. This allows some experimental fine tuning by end users to overcome quirky I2C device problems. Reported-by:

The encoder was not honoring the MDL size sent in DE_SET_MDL mailbox commands. This change adjusts the size of the last buffer in an MDL, as reported to the firmware, so that the encoder will send the exact amount of bytes we specify per MDL transfer. This eliminates tearing in YUV playback when using non-default YUV buffer sizes. Signed-off-by:

Fix YUV capture such that the encoder will pass one frame per transfer. This will allow the application to maintain frame alignment when a transfer from the encoder is missed due to high system latency in service the CX23418 IRQ. Also force YUV buffer sizes to be specified in multiples of 33.75 kB, the smalled amount of buffer sizes need to store a complete set of HM12 4:2:0 macroblocks specifying 32 lines of the frame. A full 60Hz/525 line screen requires 15 * 33.75 kB per frame and a full 50Hz/625 line screen requires 18 * 33.75 kB per frame so the default buffer size is 3 * 33.75 kB, requiring exactly 5 or 6 buffers per MDL respectively. The bytes needed per frame and hence MDL need not be the bytes in an integer number of buffers. However, if frame artifacts are seen with scaled screen sizes, the YUV buffer size can be set 34 kB (33.75 kB) to get rid of the artifacts at the cost of more copies between the kernel and userspace.

Add debug register write interface to pac7302 to be able to set for example the edge detect mode (bit 2 register 0x55) or the test pattern (bit 0..3, register 0x72) and test overlay (bit 4, register 0x72) from the user space. Only write of register page 0 is supported by this patch. Signed-off-by: Márton NÃ

For whatever reason, the device structure pointer to videobuf_queue_vmalloc_init is typed "void *", even though it's passed right through to videobuf_queue_core_init(), which expects a struct device pointer. The other videobuf implementations use struct device *; I think vmalloc should too. Signed-off-by:
