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.
