11 | Description | |
12 | ----------- | |
13 | ||
14 | The menf21bmc is a Board Management Controller (BMC) which provides an I2C | |
15 | interface to the host to access the features implemented in the BMC. | |
16 | ||
17 | This driver gives access to the voltage monitoring feature of the main | |
18 | voltages of the board. | |
19 | The voltage sensors are connected to the ADC inputs of the BMC which is | |
20 | a PIC16F917 Mikrocontroller. | |
21 | ||
22 | Usage Notes | |
23 | ----------- | |
24 | ||
25 | This driver is part of the MFD driver named "menf21bmc" and does | |
26 | not auto-detect devices. | |
27 | You will have to instantiate the MFD driver explicitly. | |
28 | Please see Documentation/i2c/instantiating-devices for | |
29 | details. | |
30 | ||
31 | Sysfs entries | |
32 | ------------- | |
33 | ||
34 | The following attributes are supported. All attributes are read only | |
35 | The Limits are read once by the driver. | |
