| Description |
| ----------- |
| |
| This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply |
| Controller with Active-Voltage Output Control and 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. |
| |
| in[1-4]_label "vout[1-4]" |
| in[1-4]_input Measured voltage. From READ_VOUT register. |
| in[1-4]_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register. |
| in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. |
| in[1-4]_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register. |
| in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. |
| in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. |
| in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. |
| in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. |
| in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. |
| in[1-4]_highest Historical maximum voltage. |
| in[1-4]_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. |
