Subject: [PATCH v2] media: dt-bindings: media: renesas,csi2: Update data-lanes property

CSI-2 (CSI4LNK0) on R-Car and RZ/G2 supports 4-lane mode which is already
handled by rcar-csi2.c driver. This patch updates the data-lanes property
to describe the same.

Hi All,

Instead of adding uniqueItems:true into SoC binding doc's I think we could
add this in video-interfaces.yaml for data-lanes property. Any thoughts on this?

Cheers,
Prabhakar

* Added uniqueItems

As repeating items are not allowed I think it's a good idea.
In the meantime this patch looks good to me

Could this be put into the schema instead? The same holds true for all
devices.

I just came across this patch [0] which does this! Hopefully this will
get merged soon. I'll resend a v3 dropping uniqueItems from
renesas,csi2.yaml.
