1/*
2 * include/linux/node.h - generic node definition
3 *
4 * This is mainly for topological representation. We define the
5 * basic 'struct node' here, which can be embedded in per-arch
6 * definitions of processors.
7 *
8 * Basic handling of the devices is done in drivers/base/node.c
9 * and system devices are handled in drivers/base/sys.c.
10 *
11 * Nodes are exported via driverfs in the class/node/devices/
12 * directory.
13 *
14 * Per-node interfaces can be implemented using a struct device_interface.
15 * See the following for how to do this:
16 * - drivers/base/intf.c
17 * - Documentation/driver-model/interface.txt
