14Description
15-----------
16
17The menf21bmc is a Board Management Controller (BMC) which provides an I2C
18interface to the host to access the features implemented in the BMC.
19
20This driver gives access to the voltage monitoring feature of the main
21voltages of the board.
22The voltage sensors are connected to the ADC inputs of the BMC which is
23a PIC16F917 Mikrocontroller.

25Usage Notes
26-----------
27
28This driver is part of the MFD driver named "menf21bmc" and does
29not auto-detect devices.
30You will have to instantiate the MFD driver explicitly.
31Please see Documentation/i2c/instantiating-devices.rst for
32details.
