Subject[PATCHv2 0/8] videobuf2: support new noncontiguous DMA API
Date
Hello,

The series adds support for noncontiguous DMA API and adds
V4L2_MEMORY_FLAG_NON_COHERENT UAPI.

v2:
-- addressed review feedback [0] (Hans, Tomasz)
-- inverted and renamed vb2_queue.non_coherent_mem member. It's easier
when we have vb2_queue.coherent_mem instead
-- inverted and renamed the corresponding vb2_dc_buf.non_coherent_mem
member, for pretty much same reason.

IOW some semi-intrusive changes.
