|  | ---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. |

|  | --- 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. |
