There was a bug where enumerating the i2c for devices would result in false positives. The root of the issue was the scanning was using SMBUS_QUICK messages, which are zero length write requests (which our i2c adapter implementation didn't handle). Because we never strobed any bytes onto the bus, the status register would still contain the value from the previous request.

Prior to now, we never relied on the Hauppauge tveeprom to identify which tuner is associated with the board. Now that the HVR-950q determines what the tuner is based on the eeprom, set the tuner ID appropriately. Thanks to Michael Krufky <mkrufky@linuxtv.org> for providing information on the tveeprom organization. Signed-off-by:

Rework the way boards are managed so that we can change the board description based on the Hauppauge eeprom (modeled after cx88-cards.c). Also, make sure that we don't load the analog stack if there are no analog inputs defined in the board profile. Thanks to Michael Krufky <mkrufky@linuxtv.org> for providing information on the various ways different Hauppauge boards can be configured. Signed-off-by:

There is an issue related to the i2c clock for addressing the xc5000. The au0828 chip does not support clock stretching, which the xc5000 makes use of. This results in cases where we silently get back garbage in i2c read operations. To work around this issue until we slow down the i2c clock when talking with that specific device. This was not an issue before we had analog support because we never needed to enumerate the i2c bus, and digital tuning never actually needed to perform read operations against the xc5000.

For the i2c messages to read and write registers, the two high order bits of the first byte dictates whether it is a read or a write operation.

The xc5000 driver has a bug where the IF is always set to whatever the first caller to dvb_attach() provides. This fails when the device requires an IF other than 5380 and the analog driver is loaded first through tuner-core (which always supplies the hard-coded value of 5380).

This addition to the v4l2-api add definitions for the constants and data structures used for sliced VBI data insertion into MPEG streams triggered by V4L2_MPEG_STREAM_VBI_FMT_IVTV. This simply declares what the ivtv and cx18 drivers and MythTV have already been doing and provides a proper data structure definition to user space. Signed-off-by:

Some Phytec cameras have a I2C GPIO expander which allows it to switch between different sensor bus widths. This was previously handled in the camera driver. Since handling of this switch varies on several boards the cameras are used on, the board support seems a better place to handle the switch Signed-off-by:

Camera sensors have a native bus width say support, but on some boards not all sensor data lines are connected to the image interface and thus support a different bus width than the sensors native one. Some boards even have a bus driver which dynamically switches between different bus widths with a GPIO. This patch adds a hook which board code can use to support different bus widths. Signed-off-by:

Make sure videobuf_waiton() is used before freeing a buffer. Without this fix we may return the buffer to the allocator before the bus mastering operation is finished. Reported-by:

Currently soc-camera doesn't set up any image format without an explicit S_FMT. According to the API this should be supported, for example, capture-example.c from v4l2-apps by default doesn't issue an S_FMT. This patch moves negotiating of available host-camera format translations to probe() time, and restores the state from the last close() on the next open(). This is needed for some drivers, which power down or reset hardware after the last user closes the interface. This patch also has a nice side-effect of avoiding multiple allocation anf freeing of format translation tables. Signed-off-by:
