Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	tristate "Dallas's 1-wire support"
	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.

	bool "Userspace communication over connector"
	default y
	help
	  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.
