| Description
 | |
| -----------
 | |
| 
 | |
| The menf21bmc is a Board Management Controller (BMC) which provides an I2C
 | |
| interface to the host to access the features implemented in the BMC.
 | |
| 
 | |
| This driver gives access to the voltage monitoring feature of the main
 | |
| voltages of the board.
 | |
| The voltage sensors are connected to the ADC inputs of the BMC which is
 | |
| a PIC16F917 Mikrocontroller.
 | |
| 
 | |
| Usage Notes
 | |
| -----------
 | |
| 
 | |
| This driver is part of the MFD driver named "menf21bmc" and does
 | |
| not auto-detect devices.
 | |
| You will have to instantiate the MFD driver explicitly.
 | |
| Please see Documentation/i2c/instantiating-devices for
 | |
| details.
 | |
| 
 | |
| Sysfs entries
 | |
| -------------
 | |
| 
 | |
| The following attributes are supported. All attributes are read only
 | |
| The Limits are read once by the driver.
