11 - Errors in regulator configuration can have very serious consequences
13 - It is not possible to automatically determine the power configuration
14 of the system - software-equivalent variants of the same chip may
15 have different power requirements, and not all components with power
25 ------------------
27 - The overwhelming majority of devices in a system will have no
28 requirement to do any runtime configuration of their power beyond
31 - Many of the power supplies in the system will be shared between many
38 supplies without any additional effort.
