12 help
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
16 a GPIO.
17
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"
23 depends on GPIOLIB
24 help
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
28 through GPIO pins.
29
30 This driver can also be built as a module. If so, the module
31 will be called i2c-mux-gpio.

35 help
36 If you say yes here you get support for the NXP PCA9541
37 I2C Master Selector.
38
39 This driver can also be built as a module. If so, the module
40 will be called i2c-mux-pca9541.

45 help
46 If you say yes here you get support for the Philips PCA954x
47 I2C mux/switch devices.
48
49 This driver can also be built as a module. If so, the module
50 will be called i2c-mux-pca954x.

52config I2C_MUX_PINCTRL
53 tristate "pinctrl-based I2C multiplexer"
54 depends on PINCTRL
55 help
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.
60
61 This driver can also be built as a module. If so, the module will be
62 called pinctrl-i2cmux.

64config I2C_MUX_REG
65 tristate "Register-based I2C multiplexer"
66 help
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
70 by a single register.
71
72 This driver can also be built as a module. If so, the module
73 will be called i2c-mux-reg.

78 select OF_DYNAMIC
79 help
80 If you say yes to this option, support will be included for an I2C
81 demultiplexer that uses the pinctrl subsystem. This is useful if you
82 want to change the I2C master at run-time depending on features.
