CONFIG_W1: Dallas's 1-wire support

General informations

The Linux kernel configuration item CONFIG_W1:

• prompt: Dallas's 1-wire support
• type: tristate
• depends on: CONFIG_HAS_IOMEM
• defined in drivers/w1/Kconfig
• found in Linux kernels: 2.6.8–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: wire

Help text

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.
