Description
-----------

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

Device compliant with:

- PMBus rev 1.3 interface.

Device supports direct and linear format for reading input voltage,
output voltage, input current, output current, input power, output
power, and temperature.

The driver exports the following attributes via the 'sysfs' files
for input voltage:

**in1_input**

**in1_label**

**in1_crit**

**in1_crit_alarm**

**in1_lcrit**

**in1_lcrit_alarm**

**in1_min**

**in1_min_alarm**

The driver provides the following attributes for output voltage:

**in2_input**

**in2_min**

**in2_min_alarm**

**in3_input**

**in3_label**

**in3_crit**

**in3_crit_alarm**

**in3_lcrit**

**in3_lcrit_alarm**

**in3_min**

**in3_min_alarm**

The driver provides the following attributes for input current:

**curr1_input**

**curr1_label**

**curr1_max**

**curr1_max_alarm**

**curr2_input**
