+Regulator API design notes
+==========================
+
+This document provides a brief, partially structured, overview of some
+of the design considerations which impact the regulator API design.
+
+Safety
+------
+
+ - Errors in regulator configuration can have very serious consequences
+   for the system, potentially including lasting hardware damage.
+ - It is not possible to automatically determine the power confugration
+   of the system - software-equivalent variants of the same chip may
+   have different power requirments, and not all components with power
+   requirements are visible to software.
+
+  => The API should make no changes to the hardware state unless it has
+     specific knowledge that these changes are safe to do perform on
+     this particular system.
+
+Consumer use cases
+------------------
+
+ - The overwhelming majority of devices in a system will have no
+   requirement to do any runtime configuration of their power beyond
+   being able to turn it on or off.
+
+ - Many of the power supplies in the system will be shared between many
+   different consumers.
+
+  => The consumer API should be structured so that these use cases are
+     very easy to handle and so that consumers will work with shared
+     supplies without any additional effort.
