-+config BOARD_ATNGW100_I2C_GPIO
-+ bool "Use GPIO for i2c instead of built-in TWI module"
-+ help
-+ The driver for the built-in TWI module has been plagued by
-+ various problems, while the i2c-gpio driver is based on the
-+ trusty old i2c-algo-bit bitbanging engine, making it work
-+ on pretty much any setup.
-+
-+ Choose 'Y' here if you're having i2c-related problems and
-+ want to rule out the i2c bus driver.
