17 The menf21bmc is a Board Management Controller (BMC) which provides an I2C
18 interface to the host to access the features implemented in the BMC.
20 This driver gives access to the voltage monitoring feature of the main
21 voltages of the board.
22 The voltage sensors are connected to the ADC inputs of the BMC which is
23 a PIC16F917 Mikrocontroller.
28 This driver is part of the MFD driver named "menf21bmc" and does
29 not auto-detect devices.
30 You will have to instantiate the MFD driver explicitly.
31 Please see Documentation/i2c/instantiating-devices.rst for
37 The following attributes are supported. All attributes are read only
38 The Limits are read once by the driver.
