If the camera was set to output formats like RGB565 YUYV or SBGGR10, the resulting image was scrambled due to erroneous interpretations of horizontal parameter's units. This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings that, first are not used within mainline code and second, standing at the datasheets, they will not work properly: The IPU internal bus support only the following data formatting (44.1.1.3 Data Flows and Formats): 1 YUV 4:4:4 or RGB-8 bits per color component 2 YUV 4:4:4 or RGB-10 bits per color component 3 Generic data (from sensor to the system memory only) And format conversions are done: - from memory: unpacking from other formats to IPU supported ones - to memory: packing in the inverse order. So, assigning a packing/unpacking strategy to the IPU for those formats will produce a packing to memory and not the inverse. Signed-off-by:

The 'pix->width' field may be updated in mx3_camera_set_fmt() to fulfill the IPU stride line alignment requirements. If this update takes place, the 'fmt.pix.sizeimage' field in the struct v4l2_format stucture returned by VIDIOC_S_FMT is wrong. We need to update the 'pix->sizeimage' field in the mx3_camera_set_fmt() function to fix this issue. Signed-off-by:

Even though clk_put() is a no-op on most architectures it is not for some ARM implementations. To not fail on those, release the clock timer before freeing the surrounding structure. This bug was spotted by the semantic patch tool coccinelle using the script found at scripts/coccinelle/free/kfree.cocci. More information about semantic patching is available at http://coccinelle.lip6.fr/Signed-off-by:

Some camera systems have strong requirement for capturing an exact number of frames after starting the stream and do not tolerate losing captured frames. By starting the stream after the videobuf has queued the buffers, we ensure that no frame will be lost. Signed-off-by:

Reported by, and based on a patch from, Martin Dauskardt. The AUDIO_AC3_BITRATE control is still missing from this list, but such optional controls are a bit hard to handle. This will be fixed automatically when we switch to the control framework. Signed-off-by:

drivers/ieee1394/ has been removed in Linux 2.6.37. The corresponding backend code in firedtv is no longer built in now and can be deleted. Firedtv continues to work with drivers/firewire/. Also, fix a Kconfig menu comment: Removal of CONFIG_IEEE1394 made the "Supported FireWire (IEEE 1394) Adapters" comment disappear; bring it back with corrected dependency. Signed-off-by:

Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong type of R/W arguments. They were fixed, but the old ioctl names are still there, maintained to avoid breaking binary compatibility: There's no sense on preserving those forever, as it is very doubtful that someone would try to use a such old binary with a modern kernel. Removing them will allow us to remove some magic done at the V4L ioctl handler. Note that any application compiled with a videodev2.h from 2.6.7 or later will be using the correct ioctls.

The dabusb driver was conceived as an experimental driver for a test device. The driver never supported any shipped product, and, while there were some updates for it in 2003, for an ancient product, those changes were never submitted upstream. Also, there's no DocBook for its API, nor any upstream discussion. So it was decided to remove it in 2.6.39. Future support for a DAB API should be discussed on the linux-media list first.

This driver is for obsolete hardware that the old maintainer didn't care (or not have the hardware anymore), and that no other developer could find any hardware to buy. The V4L1 API is no longer supported, and since nobody stepped in to convert them to V4L2 the decision was made to remove them. Signed-off-by:

With the new gspca v4l2 vicam driver, there is no more reason to keep the old v4l1 usbvideo vicam driver around, and since that is the last usbvideo framework using driver, the old usbvideo framework itself can go too. Signed-off-by:

This is a complete rewrite of the old v4l1 vicam subdriver, featuring multiple resolutions, gain + exposure control and still has less code. Oh and it is a v4l2 driver rather then v4l1 ofcourse :) Many thanks to Devin Heitmueller <dheitmueller@kernellabs.com> for donating his 3com homeconnect to me, which made this rewrite possible.

v4l2-ctl and qv4l2 enumerate controls using V4L2_CTRL_FLAG_NEXT_CTRL, falling back to the old method if the flag isn't supported. The v4l2_subdev_queryctrl function will currently handle that flag, but for the controls of the subdev only. This isn't right, it should refuse this flag, otherwise v4l2-ctl will only see the controls of the first subdev. Signed-off-by:

Subdev controls return codes are evil, as they return -EINVAL to mean both unsupported and invalid arguments. Due to that, we need to use a trick to identify what controls are supported by a subdev. Signed-off-by:
