int fimc_capture_ctrls_create

(

struct fimc_dev *

fimc

)

fimc_capture_ctrls_create - initialize the control handler Initialize the capture video node control handler and fill it with the FIMC controls. Inherit any sensor's controls if the 'user_subdev_api' flag is false (default behaviour). This function need to be called with the graph mutex held.

void fimc_sensor_notify	(	struct v4l2_subdev *	sd,
		unsigned int	notification,
		void *	arg
	)

fimc_sensor_notify - v4l2_device notification from a sensor subdev : pointer to a subdev generating the notification : the notification type, must be S5P_FIMC_TX_END_NOTIFY

• : 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.
