+
+		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.

 		When a board is reset during an i2c bus transfer
