7 | Generic Voltage and Current Regulator support. | |
8 | ||
9 | This framework is designed to provide a generic interface to voltage | |
10 | and current regulators within the Linux kernel. It's intended to | |
11 | provide voltage and current control to client or consumer drivers and | |
12 | also provide status information to user space applications through a | |
13 | sysfs interface. | |
14 | ||
15 | The intention is to allow systems to dynamically control regulator | |
16 | output in order to save power and prolong battery life. This applies | |
17 | to both voltage regulators (where voltage output is controllable) and | |
18 | current sinks (where current output is controllable). | |
19 | ||
20 | This framework safely compiles out if not selected so that client | |
21 | drivers can still be used in systems with no software controllable | |
22 | regulators. | |
23 | ||
24 | If unsure, say no. | |

41 | help | |
42 | This driver provides a virtual consumer for the voltage and | |
43 | current regulator API which provides sysfs controls for | |
44 | configuring the supplies requested. This is mainly useful | |
45 | for test purposes. | |

47 | If unsure, say no. | |
