Configuration File Format
The configuration file format for the i2c busses is strict. Dell recommends using i2ctool --create to create a boilerplate
configuration file and editing the boilerplate configuration file rather than creating it from scratch.
The configuration file lists each bus from 0 to 4 and the devices. The number of devices MUST match the number of entries or
the i2ctool stops functioning. If you edit out a device or add a device, you must adjust the number of devices found.
