Subject[PATCH 0/9] media: imx: Add better OF graph support
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 patches submitted earlier:

"[PATCH v2] media: staging/imx: do not return error in link_notify for unknown sources"
"[PATCH RFC] media: staging/imx: fix complete handler"
