Tegra210 contains VI controller for video input capture from MIPI CSI camera sensors and also supports built-in test pattern generator. CSI ports can be one-to-one mapped to VI channels for capturing from an external sensor or from built-in test pattern generator. This patch adds support for VI and CSI and enables them in Tegra210 device tree.
