- Tegra210 has CSI part of VI sharing same host interface and register space.
So, VI device node should have CSI child node.

vi can have optional ports node and max 6 ports are supported. Each port
should have single 'endpoint' child node. All port nodes are grouped under
ports node. Please refer to the bindings defined in

channel (optional nodes)
Maximum 6 channels are supported with each csi brick as either x4 or x2
based on hw connectivity to sensor.
Required properties:
- reg: csi port number. Valid port numbers are 0 through 5.
- nvidia,mipi-calibrate: Should contain a phandle and a specifier
specifying which pads are used by this CSI port and need to be
calibrated. See also ../display/tegra/nvidia,tegra114-mipi.txt.
Each channel node must contain 2 port nodes which can be grouped
under 'ports' node and each port should have a single child 'endpoint'
node.
ports node
Please refer to the bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt
ports node must contain below 2 port nodes.
port@0 with single child 'endpoint' node always a sink.
port@1 with single child 'endpoint' node always a source.
port@0 (required node)
Required properties:
- reg: 0
endpoint (required node)
Required properties:
- data-lanes: an array of data lane from 1 to 4. Valid array
lengths are 1/2/4.
- remote-endpoint: phandle to sensor 'endpoint' node.
