+Description: Bus scanning interval, microseconds component.
+ Some of 1-Wire devices commonly associated with physical access
+ control systems are attached/generate presence for as short as
+ 100 ms - hence the tens-to-hundreds milliseconds scan intervals
+ are required.
+ see Documentation/w1/w1.generic for detailed information.
+Users: any user space application which wants to know bus scanning
+ interval
