/*
|
||
|
|
* include/linux/node.h - generic node definition
|
||
|
|
*
|
||
|
|
* This is mainly for topological representation. We define the
|
||
|
|
* basic 'struct node' here, which can be embedded in per-arch
|
||
|
|
* definitions of processors.
|
||
|
|
*
|
||
|
|
* Basic handling of the devices is done in drivers/base/node.c
|
||
|
|
* and system devices are handled in drivers/base/sys.c.
|
||
|
|
*
|
||
|
|
* Nodes are exported via driverfs in the class/node/devices/
|
||
|
|
* directory.
|
||
|
|
*
|
||
|
|
* Per-node interfaces can be implemented using a struct device_interface.
|
||
|
|
* See the following for how to do this:
|
||
|
|
* - drivers/base/intf.c
|
||
|
|
* - Documentation/driver-model/interface.txt
