+          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.
