CONFIG_MUX_MMIO: MMIO/Regmap register bitfield-controlled Multiplexer

General informations

The Linux kernel configuration item CONFIG_MUX_MMIO has multiple definitions:

MMIO/Regmap register bitfield-controlled Multiplexer found in drivers/mux/Kconfig

The configuration item CONFIG_MUX_MMIO:

• prompt: MMIO/Regmap register bitfield-controlled Multiplexer
• type: tristate
• depends on: CONFIG_OF
• defined in drivers/mux/Kconfig
• found in Linux kernels: 5.3–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: mux-mmio

Help text

MMIO/Regmap register bitfield-controlled Multiplexer controller.

The driver builds multiplexer controllers for bitfields in either a syscon register or a driver regmap register. For N bit wide bitfields, there will be 2^N possible multiplexer states.

To compile the driver as a module, choose M here: the module will be called mux-mmio.
