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.

I2C busses connected through a MUX, which in turn is controlled

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 i2c-mux-pinctrl.
