options I2C_SCAN
The iic driver provides a uniform programming interface layer between I2C master controllers and various I2C slave devices. Each I2C master controller attaches an iic framework; several slave devices can then be attached to the iic bus.
All I2C slave devices are uniquely identified by the address on the bus. The master accesses a particular slave device using its address.
System Management Bus (SMBus) protocol is also supported by emulating it with the I2C commands.
