+	depends on HAS_IOMEM
+	---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.

+	default y
+	---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.
