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 || COMPILE_TEST
13 If you say yes to this option, support will be included for an
14 I2C multimaster arbitration scheme using GPIOs and a challenge &
15 response mechanism where masters have to claim the bus by asserting
18 This driver can also be built as a module. If so, the module
19 will be called i2c-arb-gpio-challenge.
22 tristate "GPIO-based I2C multiplexer"
25 If you say yes to this option, support will be included for a
26 GPIO based I2C multiplexer. This driver provides access to
27 I2C busses connected through a MUX, which is controlled
30 This driver can also be built as a module. If so, the module
31 will be called i2c-mux-gpio.
33 config I2C_MUX_PCA9541
34 tristate "NXP PCA9541 I2C Master Selector"
36 If you say yes here you get support for the NXP PCA9541
39 This driver can also be built as a module. If so, the module
40 will be called i2c-mux-pca9541.
42 config I2C_MUX_PCA954x
43 tristate "Philips PCA954x I2C Mux/switches"
44 depends on GPIOLIB || COMPILE_TEST
46 If you say yes here you get support for the Philips PCA954x
47 I2C mux/switch devices.
49 This driver can also be built as a module. If so, the module
50 will be called i2c-mux-pca954x.
52 config I2C_MUX_PINCTRL
53 tristate "pinctrl-based I2C multiplexer"
56 If you say yes to this option, support will be included for an I2C
57 multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
58 This is useful for SoCs whose I2C module's signals can be routed to
59 different sets of pins at run-time.
61 This driver can also be built as a module. If so, the module will be
62 called pinctrl-i2cmux.
65 tristate "Register-based I2C multiplexer"
67 If you say yes to this option, support will be included for a
68 register based I2C multiplexer. This driver provides access to
69 I2C busses connected through a MUX, which is controlled
72 This driver can also be built as a module. If so, the module
73 will be called i2c-mux-reg.
