- The video device is not allocated when mt9t031_init() is called, don't use it in debug printk. - The clock polarity is inverted in mt9t031_set_bus_param(), use the correct one. Signed-off-by:

This patch removes the phytec specific setting of the bus width and switches to the more generic query_bus_param/set_bus_param hooks 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:

For the case, that we have to capture with a default format, i.e., when the user doesn't call S_FMT, we have to use the field value according to the default, configured at open() time. Signed-off-by:

As host and camera drivers become more complex, differences between S_FMT and S_CROP functionality grow, this patch separates them. Signed-off-by:

Bt819 needs the parent driver to drive a GPIO pin low and high in order to reset its fifo. Use the new notify callback for this. Signed-off-by:

Add a notify callback to v4l2_device to let sub-devices notify their parent of special events. Signed-off-by:
-
Hans Verkuil authored
Normally the parent device of v4l2_device is used as the video device node's parent. But if it was not set, then use the parent field in the video_device struct. This is needed in the cx88 driver, which has one core v4l2_device but creates multiple pci devices (one each for raw and mpeg video). So you cannot associate the core v4l2_device with a particular PCI device, but you can do that for each video_device. Signed-off-by:

The new support for the CX23885_BOARD_NETUP_DUAL_DVBS2_CI board broke the existing boards. Interrupts for the netup part were enabled and handled without testing whether the current board actually had a netup -> instant and fatal crash. I've added tests to do this only for the CX23885_BOARD_NETUP_DUAL_DVBS2_CI board. Signed-off-by:

Fix a bug where all frame headers were being discarded, instead of being part of the stream output, on MR97310A cameras. The frame headers contain information which may be useful in processing the video output and therefore should be kept and not discarded. A corresponding patch to the decompression algorithm in libv4lconvert/mr97310a.c corrects the change in frame offset. Signed-off-by:

Setting state->frontend.demodulator_priv to NULL in the event of a kzalloc error will result in an OOPS. Just remove that line. Thanks to Matthias Schwarzott for pointing this out. Cc: Matthias Schwarzott <zzam@gentoo.org> Signed-off-by:

The vfl_type field is set by the core, so anything you fill in here will be overwritten. And it will be set to a VFL_TYPE_ value, not a VID_TYPE_ value which is an obsolete V4L1 type. Since these V4L1 types have been made unavailable for V4L2 drivers, this driver stopped compiling. In this case the fix is just removing this assignment.
