This one is high on my list of unfortunate name clashes. Many NXP SoCs (among others, I've seen that in other vendors too) have IP cores named "Camera Sensor Interface" that they abbreviate to "CSI". They are unrelated to the MIPI Camera Serial Interface. I won't blame NXP, as I think they may have started using the acronym before MIPI CSI became a big thing. -- Regards, Laurent Pinchart
