[PATCH v9 0/4] Add Rockchip RGA V4l2 support




This patch series add a v4l2 m2m drvier for rockchip RGA direct rendering based 2d graphics acceleration module.

Recently I tried to add protduff support for gstreamer on rockchip platform, and i found that API 
were not very suitable for my purpose. 
It shouldn't go upstream until we can figure out what people need, 

change in V9:
- remove protduff things
- test with the latest v4l2-compliance

change in V8:
- remove protduff things

change in V6,V7:
- correct warning in checkpatch.pl

change in V5:
- v4l2-compliance: handle invalid pxielformat 
- v4l2-compliance: add subscribe_event
- add colorspace support

change in V4:
- document the controls.
- change according to Hans's comments

change in V3:
- rename the controls.
- add pm_runtime support.
- enable node by default.
- correct spelling in documents.

change in V2:
- generalize the controls.
- map buffers (10-50 us) in every cmd-run rather than in buffer-import to avoid get_free_pages failed on
actively used systems.
- remove status in dt-bindings examples.
