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);


  void (* 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.
