20 The intention is to allow systems to dynamically control regulator power
27 ``Documentation/power/regulator``.
30 --------
32 The regulator API uses a number of terms which may not be familiar:
34 Regulator
42 Electronic device which consumes power provided by a regulator. These
43 may either be static, requiring only a fixed supply, or dynamic,
44 requiring active management of the regulator at runtime.
