Hi All, This series enable Gen3 VIN support in rcar-vin driver for Renesas r8a7795 and r8a7796. It is based on top of v4.11-rc1. Patches that previously have been part of this series have been broken out to a separate series since they fix issues in the rcar-vin driver which are not strictly related to the Gen3 MC enablement. This series depends on that patch series which is posted separately as '[PATCH 00/16] rcar-vin: fix issues with format and capturing'. The driver is tested on both Renesas H3 (r8a7795) and M3-W (r8a7796) together with the rcar-csi2 driver (posted separately) and a prototype driver of the ADV7482 (not ready for upstream but publicly available). It is possible to capture both CVBS and HDMI video streams, v4l2-compliance passes with no errors and media-ctl can be used to change the routing and formats for the different entities in the media graph. Gen2 compatibility is verified on Koelsch and no problems where found, video can be captured just like before and v4l2-compliance passes without errors or warnings. I have started on a very basic test suite for the VIN driver at: https://git.ragnatech.se/vin-tests And as before the state of the driver and information about how to test it can be found on the elinux wiki: http://elinux.org/R-Car/Tests:rcar-vin * Changes since v3 - Only add neighboring subdevices to the async notifier. Instead of parsing the whole OF graph depend on incremental async subnotifier to discover the whole pipeline. This is needed to support arbitrarily long graphs and support the new ADV7482 prototype driver which Kieran is working on. - Fix warning from lockdep, reported by Kieran. - Fix commit messeges from feedback from Sergei, thanks. - Fix chip info an OF device ids sorting order, thanks Geert. - Use subdev->of_node instead of subdev->dev->of_node, thanks Kieran. * Changes since v2 - Do not try to control the subdevices in the media graph from the rcar-vin driver. Have user-space configure to format in the pipeline instead. - Add link validation before starting the stream. - Rework on how the subdevices are and the video node behave by defining specific V4L2 operations for the MC mode of operation, this simplified the driver quit a bit, thanks Laurent! - Add a new 'renesas,id' DT property which is needed to to be able to keep the VIN to CSI-2 routing table inside the driver. Previously this information was taken from the CSI-2 DT node which is obviusly the wrong way to do things. Thanks Laurent for pointing this out. - Fixed a memory leek in the group allocator function. - Return -EMLINK instead of -EBUSY if a MC link is not possible given the current routing setup. - Add comments to clarify that the 4 channels from the CSI-2 node is not directly related to CSI-2 virtual channels, the CSI-2 node can output any VC on any of its output channels. * Changes since v1 - Remove unneeded casts as pointed out by Geert. - Fix spelling and DT documentation as pointed out by Geert and Sergei, thanks! - Refresh patch 2/32 with an updated version, thanks Sakari for pointing this out. - Add Sakaris Ack to patch 1/32. - Rebase on top of v4.9-rc1 instead of v4.9-rc3 to ease integration testing together with renesas-drivers tree.
