└─>Dallas's 1-wire support
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Dallas' 1-wire bus is useful to connect slow 1-pin devices
such as iButtons and thermal sensors.

If you want W1 support, you should say Y here.

This W1 support can also be built as a module. If so, the module
will be called wire.ko.
