[media] omap3isp: Move to videobuf2

2014-05-25T14:38:53+00:00

Replace the custom buffers queue implementation with a videobuf2 queue. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Move queue irqlock to isp_video structure

2014-05-25T14:32:08+00:00

This prepares for the move to videobuf2. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Move queue mutex to isp_video structure

2014-05-25T14:19:48+00:00

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

2014-05-25T14:19:08+00:00

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

2014-05-25T14:18:42+00:00

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()

2014-05-25T14:17:37+00:00

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

2014-05-25T14:17:14+00:00

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.

[media] omap3isp: queue: Fix the dma_map_sg() return value check

2014-05-25T14:16:18+00:00

dma_map_sg() can merge sglist entries, and can thus return a number of mapped entries different than the original value. Don't consider this as an error. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Allocate kernel buffers with dma_alloc_coherent

2014-05-25T14:15:47+00:00

And retrieve the related sg table using dma_get_sgtable(). Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: queue: Inline the ispmmu_v(un)map functions

2014-05-25T14:15:08+00:00

The ispmmu_vmap() and ispmmu_vunmap() functions are just wrappers around omap_iommu_vmap() and omap_iommu_vunmap(). Inline them. Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
