53  * STARTING - Capture starting up
54  * RUNNING  - Operation in progress have buffers
55  * STOPPING - Stopping operation
71  * FULL - One capture fills the whole vb2 buffer
72  * HALF_TOP - One capture fills the top half of the vb2 buffer
73  * HALF_BOTTOM - One capture fills the bottom half of the vb2 buffer
82  * struct rvin_video_format - Data format stored in memory
92  * struct rvin_parallel_entity - Parallel video input endpoint descriptor
93  * @asd:	sub-device descriptor for async framework
113  * struct rvin_group_route - describes a route from a channel of a
114  *	CSI-2 receiver to a VIN
116  * @csi:	CSI-2 receiver ID.
117  * @channel:	Output channel of the CSI-2 receiver.
120  *		allow for a route from @csi + @chan to @vin.
123  *	Each R-Car CSI-2 receiver has four output channels facing the VIN
124  *	devices, each channel can carry one CSI-2 Virtual Channel (VC).
125  *	There is no correlation between channel number and CSI-2 VC. It's
126  *	up to the CSI-2 receiver driver to configure which VC is output
130  *	allow for the same route from @csi + @channel to @vin. For example
131  *	on R-Car H3 both the CHSEL values 0 and 3 allow for a route from
137 	enum rvin_csi_id csi;  member
144  * struct rvin_info - Information about the particular VIN implementation
150  * @routes:		list of possible routes from the CSI-2 recivers to
164  * struct rvin_dev - Renesas VIN device structure
176  * @group:		Gen3 CSI group
191  * @is_csi:		flag to mark the VIN as using a CSI-2 subdevice
