| 4 | Generic Voltage and Current Regulator support. |
| 5 | |
| 6 | This framework is designed to provide a generic interface to voltage |
| 7 | and current regulators within the Linux kernel. It's intended to |
| 8 | provide voltage and current control to client or consumer drivers and |
| 9 | also provide status information to user space applications through a |
| 10 | sysfs interface. |
| 11 | |
| 12 | The intention is to allow systems to dynamically control regulator |
| 13 | output in order to save power and prolong battery life. This applies |
| 14 | to both voltage regulators (where voltage output is controllable) and |
| 15 | current sinks (where current output is controllable). |
| 16 | |
| 17 | This framework safely compiles out if not selected so that client |
| 18 | drivers can still be used in systems with no software controllable |
| 19 | regulators. |
| 20 | |
| 21 | If unsure, say no. |
