+ CONFIG_SOFT_I2C_GPIO_SCL / CONFIG_SOFT_I2C_GPIO_SDA
+
+ If your arch supports the generic GPIO framework (asm/gpio.h),
+ then you may alternatively define the two GPIOs that are to be
+ used as SCL / SDA. Any of the previous I2C_xxx macros will
+ have GPIO-based defaults assigned to them as appropriate.
+
+ You should define these to the GPIO value as given directly to
+ the generic GPIO functions.
