It's I2C driver. I'm not sure about auto-probing because something should provide information about device to Linux. It's possible to detect/scan whether there is device sitting on I2C address, but there is no auto-discovery mechanism, AFAIK.
TPS80031 device will fail to bind to this driver because it explicitly requires platform data which should be NULL if device is probed solely by I2C ID.
