| Description |
| ----------- |
| |
| This driver supports hardware monitoring for Analog Devices MAX20830, MAX20830C |
| and MAX20840C. These are Step-Down Switching Regulator with PMBus Interface. |
| |
| MAX20830, and MAX20830C are 2.7V to 16V, 30A fully integrated step-down DC-DC |
| switching regulators. MAX20840C is similar but can reach 40A. Through the PMBus |
| interface, these devices can monitor input/output voltages, output current and |
| temperature. |
| |
| The driver is a client driver to the core PMBus driver. Please see |
| Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
