| Description |
| ----------- |
| |
| The menf21bmc is a Board Management Controller (BMC) which provides an I2C |
| interface to the host to access the features implemented in the BMC. |
| |
| This driver gives access to the voltage monitoring feature of the main |
| voltages of the board. |
| The voltage sensors are connected to the ADC inputs of the BMC which is |
| a PIC16F917 Mikrocontroller. |
| |
| Usage Notes |
| ----------- |
| |
| This driver is part of the MFD driver named "menf21bmc" and does |
| not auto-detect devices. |
| You will have to instantiate the MFD driver explicitly. |
| Please see Documentation/i2c/instantiating-devices for |
| details. |
