+TODO list
+* Currently driver supports Tegra build-in TPG Only with direct media links from CSI to VI.
+  Update the driver to do TPG Vs Sensor media links based on the kernel config CONFIG_VIDEO_TEGRA_TPG.
+* Add real camera sensor capture support
+* Add RAW10 packed video format support to Tegra210 video formats
+* Add Tegra CSI MIPI pads calibration
+* Add MIPI clock Settle time computation based on the data rate
+* Add support for Ganged mode
+* Make sure v4l2-compliance tests pass with all of the above implementations.
+* Add SMMU support for VI to avoid cma_alloc failures with higher resolutions of some video formats.
