Description |
|
----------- |
|
|
|
This driver implements support for Monolithic Power Systems, Inc. (MPS) |
|
vendor dual-loop, digital, multi-phase controller MP2888. |
|
|
|
This device: supports: |
|
|
|
- One power rail. |
|
- Programmable Multi-Phase up to 10 Phases. |
|
- PWM-VID Interface |
|
- One pages 0 for telemetry. |
|
- Programmable pins for PMBus Address. |
|
- Built-In EEPROM to Store Custom Configurations. |
|
|
|
Device complaint with: |
|
|
|
- PMBus rev 1.3 interface. |
|
|
|
Device supports direct format for reading output current, output voltage, |
|
input and output power and temperature. |
|
Device supports linear format for reading input voltage and input power. |
|
|
|
The driver provides the next attributes for the current: |
|
|
|
- for current out input and maximum alarm; |
|
- for phase current: input and label. |
|
|
|
The driver exports the following attributes via the 'sysfs' files, where: |
|
|
|
- 'n' is number of configured phases (from 1 to 10); |
|
- index 1 for "iout"; |
|
- indexes 2 ... 1 + n for phases. |
|
|
|
**curr[1-{1+n}]_input** |
|
|
|
**curr[1-{1+n}]_label** |
|
|
|
**curr1_max** |
|
|
|
**curr1_max_alarm** |
|
|
|
The driver provides the next attributes for the voltage: |
|
|
|
- for voltage in: input, low and high critical thresholds, low and high |
|
critical alarms; |
|
- for voltage out: input and high alarm; |
|
|
|
The driver exports the following attributes via the 'sysfs' files, where |
|
|
|
**in1_crit** |
|

|
|
|
**in2_alarm** |
|
|
|
**in2_input** |
|
|
|
**in2_label** |
|
|
|
The driver provides the next attributes for the power: |
|
|
|
- for power in alarm and input. |
|
- for power out: cap, cap alarm an input. |
|
|
|
The driver exports the following attributes via the 'sysfs' files, where |
|
- indexes 1 for "pin"; |
|
- indexes 2 for "pout"; |
