| 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. | |
