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.rst for |
|
details. |

|
Sysfs entries |
|
------------- |
|
|
|
The following attributes are supported. All attributes are read only |
|
The Limits are read once by the driver. |
