| 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** |
