tristate "Dallas's 1-wire support"
depends on HAS_IOMEM
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.
if W1
config W1_CON
depends on CONNECTOR
bool "Userspace communication over connector"
default y
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.
