Doug Andersonb81dfaa2013-04-16 06:29:00 +000011 help
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
15 a GPIO.
16
17 This driver can also be built as a module. If so, the module
18 will be called i2c-arb-gpio-challenge.

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
27 through GPIO pins.
28
29 This driver can also be built as a module. If so, the module
Jean Delvaree7065e22012-04-28 15:32:06 +020030 will be called i2c-mux-gpio.

Guenter Roeckae63b132010-10-24 18:16:58 +020034 help
35 If you say yes here you get support for the NXP PCA9541
36 I2C Master Selector.
37
38 This driver can also be built as a module. If so, the module
Wolfram Sangb4f0b742012-04-25 22:29:43 +020039 will be called i2c-mux-pca9541.

44 If you say yes here you get support for the Philips PCA954x
45 I2C mux/switch devices.

51 tristate "pinctrl-based I2C multiplexer"
52 depends on PINCTRL
53 help
54 If you say yes to this option, support will be included for an I2C
55 multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
56 This is useful for SoCs whose I2C module's signals can be routed to
57 different sets of pins at run-time.
58
59 This driver can also be built as a module. If so, the module will be
60 called pinctrl-i2cmux.
