2008-04-24V4L/DVB (7237): Convert videobuf-dma-sg to generic DMA APIGuennadi Liakhovetski
videobuf-dma-sg does not need to depend on PCI. Switch it to using generic DMA API, convert all affected drivers, relax Kconfig restriction, improve compile-time type checking, fix some Coding Style violations while at it.

2007-10-10V4L/DVB (6290): remove videobuf_set_pci_opsMauro Carvalho Chehab
Before the videobuf redesign, a procedure for re-using videobuf without PCI scatter/gather where provided by changing the pci-dependent operations by other operations. With the newer approach, those methods are obsolete and can safelly be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-09V4L/DVB (6251): Replace video-buf to a more generic approachMauro Carvalho Chehab
video-buf currently does two different tasks: - Manages video buffers with a common code that allows implementing all the V4L2 different modes of buffering; - Controls memory allocations While the first task is generic, the second were written to support PCI DMA Scatter/Gather needs. The original approach can't even work for those video capture hardware that don't support scatter/gather. I did one approach to make it more generic. While the approach worked fine for vivi driver, it were not generic enough to handle USB needs. This patch creates two different modules, one containing the generic video buffer handling (videobuf-core) and another with PCI DMA S/G. After this patch, it would be simpler to write an USB video-buf and a non-SG DMA module.
