4ba7e4763SLiam Girdwood	  Generic Voltage and Current Regulator support.
5ba7e4763SLiam Girdwood
6ba7e4763SLiam Girdwood	  This framework is designed to provide a generic interface to voltage
7ba7e4763SLiam Girdwood	  and current regulators within the Linux kernel. It's intended to
8ba7e4763SLiam Girdwood	  provide voltage and current control to client or consumer drivers and
9ba7e4763SLiam Girdwood	  also provide status information to user space applications through a
10ba7e4763SLiam Girdwood	  sysfs interface.
11ba7e4763SLiam Girdwood
12ba7e4763SLiam Girdwood	  The intention is to allow systems to dynamically control regulator
13ba7e4763SLiam Girdwood	  output in order to save power and prolong battery life. This applies
14ba7e4763SLiam Girdwood	  to both voltage regulators (where voltage output is controllable) and
15ba7e4763SLiam Girdwood	  current sinks (where current output is controllable).
16ba7e4763SLiam Girdwood
17ba7e4763SLiam Girdwood	  This framework safely compiles out if not selected so that client
18ba7e4763SLiam Girdwood	  drivers can still be used in systems with no software controllable
