* | [media] videobuf2-dma-sg: Replace vb2_dma_sg_desc with sg_table | Ricardo Ribalda | 2013-09-26 | 1 | -8/+2 |
| | | | | | | | | | | | | | | | Replace the private struct vb2_dma_sg_desc with the struct sg_table so we can benefit from all the helping functions in lib/scatterlist.c for things like allocating the sg or compacting the descriptor. marvel-ccic and solo6x10 drivers, that use this API have been updated.

* | [media] v4l: videobuf2: add DMA scatter/gather allocator | Andrzej Pietrasiewicz | 2011-03-21 | 1 | -0/+32 |
Add an implementation of DMA scatter/gather allocator and handling routines for videobuf2. For mmap operation mode it is implemented on top of alloc_page + sg_set_page/_free_page. For userptr operation mode it is implemented on top of get_user_pages + sg_set_page/put_page.
