|
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.

This allows to communicate with userspace using connector. For more
|
|
information see <file:Documentation/driver-api/connector.rst>.
|
|
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.
