Description
|
|
-----------
|
|
|
|
This driver implements support for Monolithic Power Systems, Inc. (MPS)
|
|
MP5990 and MP5998 Hot-Swap Controller.
|
|
|
|
Device compliant with:
|
|
|
|
- PMBus rev 1.3 interface.
|
|
|
|
Device supports direct and linear format for reading input voltage,
|
|
output voltage, output current, input power and temperature.
|
|
|
|
The driver exports the following attributes via the 'sysfs' files
|
|
for input voltage:
|
|
|
|
**in1_input**
|
|
|
|
**in1_label**
|
|
|
|
**in1_max**

|
|
The driver provides the following attributes for output voltage:
|
|
|
|
**in2_input**
|
|
|
|
**in2_label**
|
|
|
|
**in2_alarm**
|
|
|
|
The driver provides the following attributes for current:
|
|
|
|
**curr1_input**
|
|
|
|
**curr1_label**
|
|
|

The driver provides the following attributes for input power:
|
|
|
|
**power1_input**
|
|
|
|
**power1_label**
|
|
|
|
**power1_alarm**
|
|
|
|
The driver provides the following attributes for output power:
|
|
|
|
**power2_input**
|
|
|
|
**power2_label**
|
|
|
|
**power2_max**
|
|
|
|
**power2_max_alarm**
|

The driver provides the following attributes for temperature:
|
|
|
|
**temp1_input**
|
|
|
|
**temp1_max**
|
|
|
|
**temp1_max_alarm**
|
|
|
|
**temp1_crit**
|
|
|
|
