Sylwester Nawrocki 3c6938f805 [media] v4l2: Add polarity flag definitions for the parallel bus FIELD signal
FIELD signal is used for indicating frame field type to the frame grabber
in interlaced scan mode, as specified in ITU-R BT.601 standard.
In normal operation mode FIELD = 0 selects Field1 (odd) and FIELD = 1
selects Field2 (even). When the FIELD signal is inverted it's the other
way around.

Add corresponding flags for configuring the FIELD signal polarity,
V4L2_MBUS_FIELD_EVEN_HIGH for the standard (non-inverted) case and
V4L2_MBUS_FIELD_EVEN_LOW for inverted case.

Also add a comment about usage of V4L2_MBUS_[HV]SYNC* flags for
the hardware that uses [HV]REF signals.

Arvydas Sidorenko 7b1c8f58fc [media] stk-webcam.c: webcam LED bug fix
This is an improved version of the patch I sent a little ago.

The problem was:
	On my DC-1125 webcam chip from Syntek, whenever the webcam turns
	on, the LED light on it is turned on also and never turns off again unless
	system is shut downed or restarted.

The previous version seemed to break some other laptop webcam work. Thanks

Al Cooper 3e0ac6717b [media] media: Fix a UVC performance problem on systems with non-coherent DMA
The UVC driver uses usb_alloc_coherent() to allocate DMA data buffers.
On systems without coherent DMA this ends up allocating buffers in
uncached memory. The subsequent memcpy's done to coalesce the DMA
chunks into contiguous buffers then run VERY slowly. On a MIPS test
system the memcpy is about 200 times slower. This issue prevents the
system from keeping up with 720p YUYV data at 10fps.

The following patch uses kmalloc to alloc the DMA buffers instead of
usb_alloc_coherent on systems without coherent DMA. With this patch
the system was easily able to keep up with 720p at 10fps.

For uvc device, dev->vdev.dev is the &intf->dev,
uvc_delete code is as below:
	usb_put_intf(dev->intf);
	usb_put_dev(dev->udev);

	uvc_status_cleanup(dev);
	uvc_ctrl_cleanup_device(dev);

	if (dev->vdev.dev)
		v4l2_device_unregister(&dev->vdev);

Fix it by get_device in v4l2_device_register and put_device in v4l2_device_disconnect

Thierry Reding 6e89648195 [media] tm6000: Enable fast USB quirk on Cinergy Hybrid
The Cinergy Hybrid cards are known not to need an artificial delay after
USB accesses so the quirk can safely be enabled.

Thierry Reding 4284570836 [media] tm6000: Add fast USB access quirk
Some devices support fast access to registers using the USB interface
while others require a certain delay after each operation. This commit
adds a quirk that can be enabled by devices that don't need the delay.

Laurent Pinchart 0a54b86a71 [media] mt9t001: Aptina (Micron) MT9T001 3MP sensor driver
The MT9T001 is a parallel 3MP sensor from Aptina (formerly Micron)
controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports binning and
cropping, and the gain, exposure, test pattern and black level controls.
