This patch adds the device tree nodes for csi, video
multiplexer and mipi-csi
besides the graph connecting the necessary endpoints to make
the media capture
entities to work in imx7 Warp board.
Also add the pin control related with the mipi_csi in that
board.

Same comment as for the binding docs, since the CSI only has one
port,
it doesn't have to be numbered.
ack.

This is the ov2680 reset GPIO? I think this belongs into patch
12.
Yes, you are right.

What is this GPIO used for?
MKBUS_RESET and totally unrelated. I will remove it. Thanks for
notice this.
