Since this driver registers the transferfunction with kernel framework, there are only private functions in this I2C bus driver. This driver currently works only in master mode and does 7 bit adderssing only. There is no support for 10 bit addressing. The driver currently supports standard mode (100KHz) and Fast mode (400KHz) operation.
