: pointer to an u32 type integer that stores the frame payload value

The End Of Frame notification sent by sensor subdev in its still capture mode. If there is only a single VSYNC generated by the sensor at the beginning of a frame transmission, FIMC does not issue the LastIrq (end of frame) interrupt. And this notification is used to complete the frame capture and returning a buffer to user-space. Subdev drivers should call this notification from their last 'End of frame capture' interrupt.
