Description¶

The menf21bmc is a Board Management Controller (BMC) which provides an I2Cinterface to the host to access the features implemented in the BMC.

This driver gives access to the voltage monitoring feature of the mainvoltages of the board.The voltage sensors are connected to the ADC inputs of the BMC which isa PIC16F917 Mikrocontroller.

Usage Notes¶

This driver is part of the MFD driver named “menf21bmc” and doesnot auto-detect devices.You will have to instantiate the MFD driver explicitly.Please seeHow to instantiate I2C devices fordetails.
