CONFIG_I2C_ARB_GPIO_CHALLENGE: GPIO-based I2C arbitration

General informations

The Linux kernel configuration item CONFIG_I2C_ARB_GPIO_CHALLENGE:

• prompt: GPIO-based I2C arbitration
• type: tristate
• depends on: ( CONFIG_GPIOLIB || CONFIG_COMPILE_TEST ) && ( CONFIG_OF )
• defined in drivers/i2c/muxes/Kconfig
• found in Linux kernels: 3.10–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.13, 6.14-rc+HEAD
• modules built: i2c-arb-gpio-challenge

Help text

If you say yes to this option, support will be included for an I2C multimaster arbitration scheme using GPIOs and a challenge & response mechanism where masters have to claim the bus by asserting a GPIO.

This driver can also be built as a module. If so, the module will be called i2c-arb-gpio-challenge.
