This is needed for the next patch where the dma-sg alloc memop needs to know the dma_dir. Signed-off-by:

The 'write' argument is very ambiguous. I first assumed that if it is 1, then we're doing video output but instead it meant the reverse. Since it is used to setup the dma_dir value anyway it is now replaced by the correct dma_dir value which is unambiguous. Signed-off-by:

videobuf2 requires drivers to give back ownership of all queue buffers in the stop_streaming operation, as well as in the start_streaming operation in case of failure. Mark all queued buffers as done in the error or queued state. Signed-off-by:

This brings the function name in line with the V4L2 API terminology and allows removing the duplicate queue type check. Signed-off-by:

When releasing the file handle the driver calls the vb2_queue_release which turns the stream off. There's thus no need to turn the stream off explicitly beforehand. Signed-off-by:

To work propertly the videobuf2 core code needs to be in charge of stream start/stop control. Implement the start_streaming and stop_streaming vb2 operations and move video enable/disable code to them. Signed-off-by:

In order to make use of the vb2 queue start/stop_streaming operations the video and queue enable/disable operations need to be split, as the vb2 queue will need to enable and disable video instead of the other way around. Also move buffer queue disable outside of uvc_video_resume() to remove all queue disable operations out of uvc_video.c. Signed-off-by:

Simplify ioctl handling by using video_ioctl2. Signed-off-by:

Laurent Pinchart authored
The v4l2_device structure embed a v4l2_prio_state structure used by default for priority handling, but drivers can override that default by setting the video_dev prio pointer to a different v4l2_prio_state instance. However, the VIDIO_G_PRIORITY and VIDIOC_S_PRIORITY implementations use the prio state embedded in v4l2_device unconditionally, breaking drivers that need to override the default. Fix them.

The fix is simply rearrange the call orders in uvc_delete() so that the child is removed before the parent.

Never use sg++, always use sg = sg_next(sg). Scatterlist entries can be combined if the memory is contiguous but sg++ won't know about that. As far as I can tell cx88 and ivtv are really broken because of this, and bttv and cx25821 are OK because vb1 doesn't combine scatterlist entries. But regardless, sg++ should never be used, only sg_next is safe. Signed-off-by:

In smipcie.c, the function i2c_bit_add_bus() is called. This function is defined by the I2C bit-banging interfaces enabled with CONFIG_I2C_ALGOBIT. As there was no dependency in Kconfig, CONFIG_I2C_ALGOBIT could be set to "m" while CONFIG_DVB_SMIPCIE was set to "y", resulting in a build error due to an undefined reference. This patch adds the dependency on CONFIG_I2C_ALGOBIT in Kconfig by selecting it when CONFIG_DVB_SMIPCIE is selected. Signed-off-by:

There is RTL2832P devices having extra MN88473 demodulator. This patch add support for such configuration. Logically MN88473 slave demodulator is connected to RTL2832 master demodulator, both I2C bus and TS input. RTL2832 is integrated to RTL2832U and RTL2832P chips.

The omap2 camera driver and the tcm825x sensor driver have been deprecated for a year and are now being removed. They are unmaintained and they use an internal API that has long since been superseded by a much better API. Worse, that internal API has been abused by out-of-kernel trees (i.MX6). In addition, Sakari stated that these drivers have never been in a usable state in the mainline kernel due to missing platform data. Signed-off-by:
