13 Interface notes
14 ---------------
15 The low speed I/O connector supported as per table below. 
16 This assumes default BIOS settings, as they are not dynamcially detected 
17 If any changes are mode (Device Manager -> System Setup -> South Cluster -> LPSS & CSS) 
18 them mraa calls will not behave as expected.
19
20 Documentation shows i2c on bus #5, ACPI shows it on bus #6, but driver uses bus #7.
