- config I2C_ARB_GPIO_CHALLENGE
- tristate "GPIO-based I2C arbitration"
- depends on GPIOLIB || COMPILE_TEST
- depends on OF
- help
- 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.
- config I2C_MUX_GPIO
- tristate "GPIO-based I2C multiplexer"
- depends on GPIOLIB
- help
- If you say yes to this option, support will be included for a
- GPIO based I2C multiplexer. This driver provides access to
- I2C busses connected through a MUX, which is controlled
- through GPIO pins.
- This driver can also be built as a module. If so, the module
- will be called i2c-mux-gpio.
- config I2C_MUX_PCA9541
- tristate "NXP PCA9541 I2C Master Selector"
- help
- If you say yes here you get support for the NXP PCA9541
- I2C Master Selector.
- This driver can also be built as a module. If so, the module
- will be called i2c-mux-pca9541.
- config I2C_MUX_PCA954x
- tristate "Philips PCA954x I2C Mux/switches"
- depends on GPIOLIB || COMPILE_TEST
- help
- If you say yes here you get support for the Philips PCA954x
- I2C mux/switch devices.
- This driver can also be built as a module. If so, the module
- will be called i2c-mux-pca954x.
- config I2C_MUX_PINCTRL
- tristate "pinctrl-based I2C multiplexer"
- depends on PINCTRL
- help
- If you say yes to this option, support will be included for an I2C
- multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
- This is useful for SoCs whose I2C module's signals can be routed to
- different sets of pins at run-time.
- This driver can also be built as a module. If so, the module will be
- called pinctrl-i2cmux.
- config I2C_MUX_REG
- tristate "Register-based I2C multiplexer"
- depends on HAS_IOMEM
- help
- If you say yes to this option, support will be included for a
- register based I2C multiplexer. This driver provides access to
- I2C busses connected through a MUX, which is controlled
- by a single register.
- This driver can also be built as a module. If so, the module
- will be called i2c-mux-reg.
