| Description |
| ----------- |
| |
| This driver implements support for TI TPS25990 eFuse. |
| This is an integrated, high-current circuit protection and power |
| management device with PMBUS interface |
| |
| Device compliant with: |
| |
| - PMBus rev 1.3 interface. |
| |
| Device supports direct format for reading input voltages, |
| output voltage, input current, input power and temperature. |
| |
| Due to the specificities of the chip, all history reset attributes |
| are tied together. Resetting the history of a sensor, resets the |
| history of all the sensors. |
| |
| The driver exports the following attributes via the 'sysfs' files |
| for input current: |
| |
| **curr1_average** |
| |
| **curr1_crit** |
| |
| **curr1_crit_alarm** |
| |
| **curr1_highest** |
| |
| **curr1_input** |
| |
| **curr1_label** |
| |
| **curr1_max** |
| |
| **curr1_max_alarm** |
| |
| **curr1_reset_history** |
| |
| The driver provides the following attributes for main input voltage: |
| |
| **in1_average** |
| |
| **in1_crit** |
| |
| **in1_crit_alarm** |
| |
| **in1_highest** |
| |
| **in1_input** |
| |
| **in1_label** |
| |
| **in1_lcrit** |
| |
| **in1_lcrit_alarm** |
| |
| **in1_lowest** |
| |
| **in1_max** |
| |
| **in1_max_alarm** |
| |
| **in1_min** |
| |
| **in1_min_alarm** |
| |
| **in1_reset_history** |
| |
| The driver provides the following attributes for auxiliary input voltage: |
| |
| **in2_input** |
| |
| **in2_label** |
| |
| The driver provides the following attributes for output voltage: |
| |
| **in3_average** |
| |
| **in3_input** |
| |
| **in3_label** |
| |
| **in3_lowest** |
| |
| **in3_min** |
| |
| **in3_min_alarm** |
| |
| **in3_reset_history** |
| |
| The driver provides the following attributes for input power: |
| |
| **power1_alarm** |
| |
| **power1_average** |
| |
| **power1_input** |
| |
| **power1_input_highest** |
| |
| **power1_label** |
| |
| **power1_max** |
| |
| **power1_reset_history** |
| |
| The driver provides the following attributes for temperature: |
| |
| **temp1_average** |
| |
| **temp1_crit** |
| |
| **temp1_crit_alarm** |
| |
| **temp1_highest** |
| |
| **temp1_input** |
| |
| **temp1_max** |
| |
| **temp1_max_alarm** |
| |
| **temp1_reset_history** |
| |
| The driver provides the following attributes for sampling: |
| |
| **samples** |
