You should mention that this is required by the device tree binding sun4i-drm,
in the second paragraph of the first section:
For all connections between components up to the TCONs in the display
pipeline, when there are multiple components of the same type at the
same depth, the local endpoint ID must be the same as the remote
component's index.
You might also want to update the diagram for TCON TOP in the binding doc.
