| 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. |
| 46 | |
| 47 | If unsure, say no. |

| 54 | This driver controls a TI bq24022 Charger attached via |
| 55 | GPIOs. The provided current regulator can enable/disable |
