| Description | |
| ----------- | |
| This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply | |
| Controller/Monitor with PMBus Interface. | |
| The driver is a client driver to the core PMBus driver. Please see | |
| Documentation/hwmon/pmbus for details on PMBus client drivers. | |
| Usage Notes | |
| ----------- | |
| This driver does not auto-detect devices. You will have to instantiate the | |
| devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
| details. | |
| Platform data support | |
| --------------------- | |
| The driver supports standard PMBus driver platform data. | |
| Sysfs entries | |
| ------------- | |
| The following attributes are supported. Limits are read-write; all other | |
| attributes are read-only. | |
| in1_label "vout1" | |
| in1_input Measured voltage. From READ_VOUT register. | |
| in1_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register. | |
| in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. | |
| in1_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register. | |
| in1_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. | |
| in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. | |
| in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. | |
| in1_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. | |
| in1_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. | |
| in1_highest Historical maximum voltage. | |
| in1_reset_history Write any value to reset history. | |
| curr1_label "iout1" | |
| curr1_input Measured current. From READ_IOUT register. | |
| curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register. | |
| curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register. | |
| curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT register. | |
| curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status. | |
| curr1_highest Historical maximum current. | |
| curr1_reset_history Write any value to reset history. | |
| temp1_input Measured temperature. From READ_TEMPERATURE_1 register. | |
| temp1_max Maximum temperature. From OT_WARN_LIMIT register. | |
| temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. | |
| temp1_max_alarm Chip temperature high alarm. Set by comparing | |
| READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING | |
| status is set. | |
| temp1_crit_alarm Chip temperature critical high alarm. Set by comparing | |
| READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT | |
| status is set. | |
| temp1_highest Historical maximum temperature. | |
| temp1_reset_history Write any value to reset history. |
