2011-09-24[media] s5p-fimc: Convert to use generic media bus polarity flagsSylwester Nawrocki3-11/+11
Switch to generic media bus signal polarity flags and allow configuring the FIELD signal polarity. Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-09-24[media] v4l2: Add polarity flag definitions for the parallel bus FIELD signalSylwester Nawrocki1-2/+10
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.

2011-09-23[media] stk-webcam.c: webcam LED bug fixArvydas Sidorenko1-1/+10
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 to Andrea Anacleto for the bug report and solution.

2011-09-23[media] media: Fix a UVC performance problem on systems with non-coherent DMAAl Cooper1-1/+16
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.

2011-09-21[media] tm6000: Enable fast USB quirk on Cinergy HybridThierry Reding1-0/+10
The Cinergy Hybrid cards are known not to need an artificial delay after USB accesses so the quirk can safely be enabled. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-09-21[media] tm6000: Add fast USB access quirkThierry Reding2-1/+6
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.
