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
curr[1-4]_input
curr[1-4]_label
curr[1-4]_max
curr[1-4]_max_alarm
curr[3-4]_lcrit
curr[3-4]_lcrit_alarm
curr[3-4]_rated_max
The driver provides for voltage: input, critical and low critical thresholds and critical and low critical alarms. The driver exports the following attributes for via the sysfs files, where indexes 1, 2 are for "vin" and 3, 4 for "vout":
in[1-4]_min
in[1-4]_crit
in[1-4_crit_alarm
in[1-4]_input
in[1-4]_label
in[1-4]_max
in[1-4]_max_alarm
in[1-4]_min
in[1-4]_min_alarm
in[3-4]_lcrit
in[3-4]_lcrit_alarm
in[3-4]_rated_max
in[3-4]_rated_min
The driver provides for power: input and alarms. The driver exports the following attributes for via the sysfs files, where indexes 1, 2 are for "pin" and 3, 4 for "pout":
power[1-2]_alarm
power[1-4]_input
power[1-4]_label
power[1-4]_max
power[1-4]_rated_max
The driver provides for temperature: input, maximum and critical thresholds and maximum and critical alarms. The driver exports the following attributes for via the sysfs files:
temp[1-2]_crit
temp[1-2]_crit_alarm
temp[1-2]_input
temp[1-2]_max
temp[1-2]_max_alarm
