Hi all,
This series contains a few updates to the dw100 dewarper. Patches 1-2
implement V4L2 requests support and dynamic updates of the vertex map.
This enables advanced use cases like interactive pan, zoom and rotate. A
first attempt to implement the dynamic update was posted a while back in
[1] but wasn't merged due to races in the implementation. By switching
to V4L2 requests the implementation is a lot simpler now.
Patches 3-4 fix an issue on PREEMPT_RT enabled kernels. These patches
should possibly be squashed into one. I expected patch 3 to be
sufficient but during testing I hit an error condition that is worked
around in patch 4. As I don't have documentation for the hardware it is
difficult to decide on the proper fix. So feedback on that is greatly
appreciated.
Best regards,
Stefan
