STRUCT 
SUBSYS_INTERF(9) 				   Device drivers infrastructure				   STRUCT SUBSYS_INTERF(9)

NAME
       struct_subsys_interface - interfaces to device functions

SYNOPSIS
       struct subsys_interface {
	 const char * name;
	 struct bus_type * subsys;
	 struct list_head node;
	 int (* add_dev) (struct device *dev, struct subsys_interface *sif);
	 int (* remove_dev) (struct device *dev, struct subsys_interface *sif);
       };

MEMBERS
       name
	   name of the device function

       subsys
	   subsytem of the devices to attach to

       node
	   the list of functions registered at the subsystem

       add_dev
	   device hookup to device function handler

       remove_dev
	   device hookup to device function handler

DESCRIPTION
       Simple interfaces attached to a subsystem. Multiple interfaces can attach to a subsystem and its devices. Unlike drivers, they do not
       exclusively claim or control devices. Interfaces usually represent a specific functionality of a subsystem/class of devices.
