Hi Laurent, Philippe(s), I spent a few days updating my mx6-media-staging branch at git@xxxxxxxxxx:slongerbeam/linux-meibp-314.git, moved forward to latest master at 4.5-rc3. So far I have retested video capture with the SabreAuto/ADV7180 and the SabreSD/OV5640-mipi-csi2, and video capture is working fine on those platforms. There is also a mem2mem that should work fine, but haven't tested yet. I removed camera preview support. At Mentor Graphics we have made quite a few changes to ipu-v3 driver to allow camera preview to initialize and control an overlay display plane independently of imx-drm, by adding a subsystem independent ipu-plane sub-unit. Note we also have a video output overlay driver that also makes use of ipu-plane. But those changes are extensive and touch imx-drm as well as ipu-v3, so I am leaving camera preview and the output overlay driver out (in fact, camera preview is not of much utility so I probably won't bring it back in upstream version). The video capture driver is not quite ready for upstream review yet. It still: - uses the old cropping APIs but should move forward to selection APIs. - uses custom sensor subdev drivers for ADV7180 and OV564x. Still need to switch to upstream subdevs. - still does not implement the media device framework.
