| 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. |

| ---help--- |
| 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. |
