Each Tegra CSI port can be one-to-one mapped to VI channel and can capture from an external camera sensor connected to CSI or from built-in test pattern generator. Tegra210 supports built-in test pattern generator from CSI to VI. This patch adds a V4L2 media controller and capture driver support for Tegra210 built-in CSI to VI 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.
