| Description |
| ----------- |
| |
| This driver implements support for Monolithic Power Systems, Inc. (MPS) |
| MP5990 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_label** |
| |
| **in1_max** |
| |
| **in1_max_alarm** |
| |
| **in1_min** |
| |
| **in1_min_alarm** |
| |
| The driver provides the following attributes for output voltage: |
| |
| **in2_input** |
| |
| **in2_label** |
| |
| **in2_alarm** |
| |
| The driver provides the following attributes for output current: |
| |
| **curr1_input** |
| |
| **curr1_label** |
| |
| **curr1_alarm** |
| |
| **curr1_max** |
| |
| The driver provides the following attributes for input power: |
| |
| **power1_input** |
| |
| **power1_label** |
| |
| **power1_alarm** |
| |
