0014 Description
0015 -----------
0016
0017 The menf21bmc is a Board Management Controller (BMC) which provides an I2C
0018 interface to the host to access the features implemented in the BMC.
0019
0020 This driver gives access to the voltage monitoring feature of the main
0021 voltages of the board.
0022 The voltage sensors are connected to the ADC inputs of the BMC which is
0023 a PIC16F917 Mikrocontroller.
0024
0025 Usage Notes
0026 -----------
0027
0028 This driver is part of the MFD driver named "menf21bmc" and does
0029 not auto-detect devices.
0030 You will have to instantiate the MFD driver explicitly.
0031 Please see Documentation/i2c/instantiating-devices.rst for
0032 details.
