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.
