2 # Multiplexer I2C chip drivers configuration
5 menu "Multiplexer I2C Chip support"
8 config I2C_ARB_GPIO_CHALLENGE
9 tristate "GPIO-based I2C arbitration"
10 depends on GPIOLIB && OF
12 If you say yes to this option, support will be included for an
13 I2C multimaster arbitration scheme using GPIOs and a challenge &
14 response mechanism where masters have to claim the bus by asserting
17 This driver can also be built as a module. If so, the module
18 will be called i2c-arb-gpio-challenge.
21 tristate "GPIO-based I2C multiplexer"
24 If you say yes to this option, support will be included for a
25 GPIO based I2C multiplexer. This driver provides access to
26 I2C busses connected through a MUX, which is controlled
29 This driver can also be built as a module. If so, the module
30 will be called i2c-mux-gpio.
32 config I2C_MUX_PCA9541
33 tristate "NXP PCA9541 I2C Master Selector"
35 If you say yes here you get support for the NXP PCA9541
38 This driver can also be built as a module. If so, the module
39 will be called i2c-mux-pca9541.
41 config I2C_MUX_PCA954x
42 tristate "Philips PCA954x I2C Mux/switches"
45 If you say yes here you get support for the Philips PCA954x
46 I2C mux/switch devices.
48 This driver can also be built as a module. If so, the module
49 will be called i2c-mux-pca954x.
51 config I2C_MUX_PINCTRL
52 tristate "pinctrl-based I2C multiplexer"
55 If you say yes to this option, support will be included for an I2C
56 multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
57 This is useful for SoCs whose I2C module's signals can be routed to
58 different sets of pins at run-time.
60 This driver can also be built as a module. If so, the module will be
61 called pinctrl-i2cmux.
