Hi Laurent,
Thanks for your help with this. Good to see that the DU driver is
getting closer to work with the IPMMU hardware! Please see below for
some feedback from me.

Hi Sergei,
Thanks for your efforts with this driver. Nice to see that V2 is
getting in better shape.
In the future, would it be possible for you to include the patch
version number in the [PATCH] tag somehow?

SuperH Mobile CEU driver. The lowest two bits of the
address registers are fixed to zero so frame buffers
have to bit 32-bit aligned. The V4L2 mmap() case is

Zero copy video frame capture from user space using V4L2 USERPTR.
This patch adds USERPTR support to the videobuf-dma-contig buffer code.

memory, this patch modifies the videobuf-dma-contig code to only
From: Magnus Damm
Remove the videobuf-dma-contig sync operation. Sync is only needed
for noncoherent buffers, and since videobuf-dma-contig is built on
coherent memory allocators the memory is by definition always in sync.
