This is a set of patches that improve support for more complex OF graphs. Currently the imx-media driver only supports a single device with a single port connected directly to either the CSI muxes or the MIPI CSI-2 receiver input ports. There can't be a multi-port device in between. This patch set removes those limitations. For an example taken from automotive, a camera sensor or decoder could be literally a remote device accessible over a FPD-III link, via TI DS90Ux9xx deserializer/serializer pairs. This patch set would support such OF graphs. There are still some assumptions and restrictions, regarding the equivalence of device-tree ports, port parents, and endpoints to media pads, entities, and links that have been enumerated in the TODO file. This patch set supersedes the following patch submitted earlier: "[PATCH v2] media: staging/imx: do not return error in link_notify for unknown sources" Tested by: Steve Longerbeam <steve_longerbeam@xxxxxxxxxx> on SabreLite with the OV5640 Tested-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> on Nitrogen6X with the TC358743.
