Camera Standard Interface driver/implementation

Hi all,

I would like to interface ADV7280 development board from Analog Devices to Tegra TX1.
For some reason it doesn’t work, could somone please tell is there any document describing CSI interface inside Linux kernel. To be able to start debugging I would need to know where to start from inside kernel.
Is there any general document that describes Tegra kernel additions/implementations?

Thank you in advance!!
