Hello, this series adds support for parallel video input to the Gen3 version of rcar-vin driver.
Compared to v3, this new iteration closes all comments from Niklas and Sergei. As the meat of the patch series hasn't changed much, please refer to v3 cover letter for more details. The most notable change is the great simplification of the parallel input notifiers registration in [5/9], as now the media controller is initialized before parallel inputs are parsed. As the media device is now properly initialized, parallel input notifiers can be registered as soon as new input devices are discovered, without having to wait for the group notifier complete callback to be called. Thanks Niklas for pointing that out. Testing: Tested image capture on both Draak and Salvator-X M3-W with a fake parallel input device added. Test branch for Salvator-X available at git://jmondi.org d3/media-master/salvator-x-dts_csi2/m3w-add_parallel_to_dts+driver-v4 For Draak at: git://jmondi.org d3/media-master/salvator-x-dts_csi2/d3-vin-driver-v4+enable-HDMI-in-dts (sorry for the horrid branch names :) Niklas, I know you have a V3M with expansion that has both CSI-2 and parallel input. Could you give this one a spin please? No changelog reported here, except from the one reported above. Most of the other changes are minors, the most notable ones are reported in each patch commit message.
