[media] omap3isp: Cancel all queued buffers when stopping the video stream

2014-05-25T14:34:03Z

When stopping a video stream the driver waits for ongoing DMA opeations to complete for the currently active buffer, but doesn't release the non-active queued buffers. This isn't a problem in most cases as the video device is usually closed after the stream is stopped, which will release all the buffers. However the problem would generate a warning when switching to videobuf2. Fix it by cancelling all buffers after DMA operations have completed.

[media] omap3isp: queue: Don't build scatterlist for kernel buffer

2014-05-25T14:19:08Z

The scatterlist is not needed for those buffers, don't build it. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Use the ARM DMA IOMMU-aware operations

2014-05-25T14:18:42Z

Attach an ARM DMA I/O virtual address space to the ISP device. This switches to the IOMMU-aware ARM DMA backend, we can thus remove the explicit calls to the OMAP IOMMU map and unmap functions. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Use sg_alloc_table_from_pages()

2014-05-25T14:17:37Z

Replace the custom implementation with a call to the scatterlist helper function. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Map PFNMAP buffers to device

2014-05-25T14:17:14Z

Userspace PFNMAP buffers need to be mapped to the device like the userspace non-PFNMAP buffers in order for the DMA mapping implementation to create IOMMU mappings when we'll switch to the IOMMU-aware DMA mapping backend.
