Hi, This series enable Gen3 support for the rcar-vin driver. It is based on top of the media_tree. 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 1-2 picks up media entity additions from Laurent which the driver depends on. - Patch 3 picks up a fix for incorrect media bus formats. This patch is posted separately but to resolve the merge conflict it generated i included it in this series. - Patch 4-8 cleans up the driver fixing some logical, style and dependency errors that was not found before the driver was added to media_next. - Patch 9 simplifies how DT is parsed and how v4l2 async binding to subdevices are setup. A incorrect usage of of_node_put() is also fixed. - Patch 10 moves struct variables around to prepare for multiple input sources. - Patch 11-12 adds an abstraction layer between the code and which subdevices are currently used. This also fixes the problem where a subdevice could not be unbound and later rebound keeping the VIN driver working. - Patch 13 adds Gen3 Hw support. - Patch 14 is the big patch adding subdevice groups that can be shared between multiple rcar-vin instances. See commit message for much more details. - Patch 15-16 adds DT bindings for Gen3 and compatibility bindings for Gen2 and Gen3. 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 from 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 device which are not yet present in the kernel. A driver for the CSI-2 interface and a prototype for ADV7482 are posted on the media malinglist. Unfortunately the ADV7482 driver needs more support in the v4l2 framework to be able to provide two interdependent video pipelines (CVBS and HDMI). Until this is resolved the driver can be compiled for either CVBS or HDMI operation. If one have a DT that only contain CVBS configuration rcar-vin v4l2-compliance pass all test expect for controls since they are not added to the ADV7482 driver. For HDMI DT and ADV7482 compiled for HDMI instead of the default CVBS v4l2-compliance fails for controls and DV timings since some parts are missing in the ADV7482 driver. It is however possible to capture both CVBS and HDMI video using qv4l2. If one is interested to test on Gen3 without having to hunt patches look at the elinux wiki for a branch containing the latest status. http://elinux.org/R-Car/Tests:rcar-vin Changes since v1: - Address review comments from Laurent. - Split cleanup of driver to smaller chunks. - Remove initial work for v4l2 framework changes to support a pad aware s_stream operation. - Picked up patch for incorrect media bus format. - Removed Ulrich patches which now have been picked up in media_tree.
