The h.264 decoder produces capture frames that are a multiple of the macroblock

When encoding into h.264, the input frame stride needs to be a multiple of 16.

Even though the CODA h.264 decoder always decodes complete macroblocks, we can

Currently the rotator unit is used to copy decoded frames out into buffers

last decoded frame, and this frame will be copied out in a later device_run,
depending on display order, we have to store the frame type until such
This patch exports all auxiliary buffers, including SRAM, as debugfs binary
blobs for debugging purposes. It shows, for example, that psbuf currently
doesn't seem to be used at all on CODA7541, and that slicebuf and workbuf
usage is far from the maximum. It can also be used to validate SRAM size
Previously we'd add one to this value, allocating one additional, superfluous

Hi,
the following series adds initial support for the CODA960 Video
Processing Unit on i.MX6Q/D/DL/S SoCs to the coda driver.
This series contains a few fixes and preparations, the CODA960
support patch, a rework of the hardware access serialization
into a single threaded workqueue, some
bytesperline is calculated in multiple places, store it in the coda_q_data
structure. This will be more useful later when adding JPEG support.

This disables forcing IDR frames at GOP size intervals on CODA7541 and CODA960,
