TX1 ISP capability

1- TX1 has two ISP engines.
2- It supports up to 1400Mpix/s | up to 24MP sensor.
3- We provide explicit ISP support for ov5693 camera board.
4- Sure, it can handle multiplier CSI input(<=6 instances)
5- Our CSI follows MIPI spec, that means if you have a sensor with up to 4 lanes, then the bit rate it can support is 4 * 1.5Gbps = 6 Gbps.
6- Multimedia API provides API and samples for camera post processing.
