Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver implements support for Infineon Digital Multi-phase Controller
|
||
|
|
XDPE152C4 and XDPE15284 dual loop voltage regulators.
|
||
|
|
The devices are compliant with:
|
||
|
|
|
||
|
|
- Intel VR13, VR13HC and VR14 rev 1.86
|
||
|
|
converter specification.
|
||
|
|
- Intel SVID rev 1.93. protocol.
|
||
|
|
- PMBus rev 1.3.1 interface.
|
||
|
|
|
||
|
|
Devices support linear format for reading input and output voltage, input
|
||
|
|
and output current, input and output power and temperature.
|
||
|
|
|
||
|
|
Devices support two pages for telemetry.
|
||
|
|
|
||
|
|
The driver provides for current: input, maximum and critical thresholds
|
||
|
|
and maximum and critical alarms. Low Critical thresholds and Low critical alarm are
|
||
|
|
supported only for current output.
|
||
|
|
The driver exports the following attributes for via the sysfs files, where
|
||
|
|
indexes 1, 2 are for "iin" and 3, 4 for "iout":
|
||
|
|
|
||
|
|
**curr[1-4]_crit**
|
||
|
|
|
||
|
|
**curr[1-4]_crit_alarm**
|
