| Description |
| ----------- |
| |
| This driver implements support for Monolithic Power Systems, Inc. (MPS) |
| MP2891 Multi-phase Digital VR Controller. |

| |
| **curr2_input** |
| |
| **curr2_label** |
| |
| **curr2_max** |
| |
| **curr2_max_alarm** |
| |
| The driver provides the following attributes for output current: |
