SYNOPSIS

media_create_intf_link(struct media_entity * entity, struct media_interface * intf, u32 flags);

ARGUMENTS

entity

pointer to media_entity

intf

pointer to media_interface

flags

Link flags, as defined in include/uapi/linux/media.h.

VALID VALUES FOR FLAGS

The MEDIA_LNK_FL_ENABLED flag indicates that the interface is connected to the entity hardware. That's the default value for interfaces. An interface may be disabled if the hardware is busy due to the usage of some other interface that it is currently controlling the hardware. A typical example is an hybrid TV device that handle only one type of stream on a given time. So, when the digital TV is streaming, the V4L2 interfaces won't be enabled, as such device is not able to also stream analog TV or radio.

NOTE

Before calling this function, media_devnode_create should be called for the interface and media_device_register_entity should be called for the interface that will be part of the link.
