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