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 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.
