+ Some I2C bus drivers require so-called "I2C algorithm" modules
+ to work. These are basically software-only abstractions of generic
+ I2C interfaces. This option will autoselect them so that you don't
+ have to care.
+
+ Unselect this only if you need to enable additional helper
+ modules, for example for use with external I2C bus drivers.

+ In doubt, say Y.
