70 This is the isp entity. It is connected to the sensor on sink pad 0 and
71 receives the frames using the CSI-2 protocol. It is responsible of configuring
72 the CSI-2 protocol. It has a cropping capability on sink pad 0 that is
73 connected to the sensor and on source pad 2 connected to the resizer entities.
74 Cropping on sink pad 0 defines the image region from the sensor.
75 Cropping on source pad 2 defines the region for the Image Stabilizer (IS).
