From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx> Hi, This series enable Gen3 support for the rcar-vin driver. It is based on top of the media_tree: git://linuxtv.org/media_tree.git master And it depends on the first rcar-vin patch at which I hope soon will enter the media tree: https://patchwork.linuxtv.org/patch/34129/ This is a rather large patch since unfortunately the subdevice and input selection on Gen3 are much more complex than on Gen2, see individual patches for a more detailed explanation. - Patch 1-3 picks up work done by Ulrich so that effort is not wasted before the driver is updated for Gen3. - Patch 4-6 are the big patches where the driver learns how to work with Gen3. - Patch 7-8 add compatible strings for Gen3 and fallback strings that are present in the old soc-camera driver but not in this new driver. The series is tested on Koelsch for Gen2 and it works as expected. If one wants to test the HDMI input the patch 'r8a7791-koelsch.dts: add HDMI input' from Hans Verkuil are needed to add it to DT . The driver passes a v4l2-compliance on Gen2 without errors or warnings. And there are no problems grabbing frames using the CVBS or HDMI input sources using qv4l2. For Gen3 there are more drivers needed to get working video input running. To be able to grab frames drivers are needed for the R-Car CSI-2 interface and the ADV7482 devices which are not yet present in the kernel. Prototypes for thees two drivers exist and a wiki page at http://elinux.org/R-Car/Tests:rcar-vin talks about how to test it all together. Whit thees prototype drivers for CSI-2 and ADV7482 the rcar-vin driver pass the v4l2-compliance tool without errors or warnings on CVBS inputs. On HDMI inputs it complains about missing DV features, this is because the prototype ADV7482 do not yet implement thees operations and are not a fault in the rcar-vin driver. Disregarding the v4l2-compliance result there is no issue grabbing frames from both CVBS and HDMI input sources on Salvator-X. But more work is needed on the prototype drivers before they are ready to be submitted for upstream.
