11Description
12-----------
13
14The menf21bmc is a Board Management Controller (BMC) which provides an I2C
15interface to the host to access the features implemented in the BMC.
16
17This driver gives access to the voltage monitoring feature of the main
18voltages of the board.
19The voltage sensors are connected to the ADC inputs of the BMC which is
20a PIC16F917 Mikrocontroller.
21
22Usage Notes
23-----------
24
25This driver is part of the MFD driver named "menf21bmc" and does
26not auto-detect devices.
27You will have to instantiate the MFD driver explicitly.
28Please see Documentation/i2c/instantiating-devices for
29details.
