+/*
+ * 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
