        ---help---
          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.

          This allows to communicate with userspace using connector. For more
          information see <file:Documentation/connector/connector.txt>.
          There are three types of messages between w1 core and userspace:
          1. Events. They are generated each time new master or slave device found
                either due to automatic or requested search.
          2. Userspace commands. Includes read/write and search/alarm search commands.
          3. Replies to userspace commands.
