# Multiplexer I2C chip drivers configuration
#
menu "Multiplexer I2C Chip support"
depends on I2C_MUX
config I2C_ARB_GPIO_CHALLENGE
tristate "GPIO-based I2C arbitration"
depends on GPIOLIB && 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
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.
