+ * struct cam_subdev - describes a camera sub-device
+ *
+ * @pdev:                  Pointer to the platform device
+ * @sd:                    V4l2 subdevice
+ * @ops:                   V4l2 subdecie operations
+ * @internal_ops:          V4l2 subdevice internal operations
+ * @name:                  Name of the sub-device. Please notice that the name
+ *                             must be unique.
+ * @sd_flags:              Subdev flags. Can be:
+ *                             %V4L2_SUBDEV_FL_HAS_DEVNODE - Set this flag if
+ *                                 this subdev needs a device node.
+ *                             %V4L2_SUBDEV_FL_HAS_EVENTS -  Set this flag if
+ *                                 this subdev generates events.
+ * @token:                 Pointer to cookie of the client driver
+ * @ent_function:          Media entity function type. Can be:
+ *                             %CAM_IFE_DEVICE_TYPE - identifies as IFE device.
+ *                             %CAM_ICP_DEVICE_TYPE - identifies as ICP device.
+ *
+ * Each instance of a subdev driver should create this struct, either
+ * stand-alone or embedded in a larger struct. This structure should be
+ * initialized/registered by cam_register_subdev
+ *
