| 13 | Description | |
| 14 | ----------- | |
| 15 | ||
| 16 | This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply | |
| 17 | Controller with Active-Voltage Output Control and PMBus Interface. | |
| 18 | ||
| 19 | The driver is a client driver to the core PMBus driver. | |
| 20 | Please see Documentation/hwmon/pmbus for details on PMBus client drivers. | |
| 21 | ||
| 22 | ||
| 23 | Usage Notes | |
| 24 | ----------- | |
| 25 | ||
| 26 | This driver does not auto-detect devices. You will have to instantiate the | |
| 27 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
| 28 | details. | |
| 29 | ||
| 30 | ||
| 31 | Platform data support | |
| 32 | --------------------- | |
| 33 | ||
| 34 | The driver supports standard PMBus driver platform data. | |
| 35 | ||
| 36 | ||
| 37 | Sysfs entries | |
| 38 | ------------- | |
| 39 | ||
| 40 | The following attributes are supported. Limits are read-write; all other | |
| 41 | attributes are read-only. | |
| 42 | ||
| 43 | in[1-4]_label "vout[1-4]" | |
| 44 | in[1-4]_input Measured voltage. From READ_VOUT register. | |
| 45 | in[1-4]_min Minumum Voltage. From VOUT_UV_WARN_LIMIT register. | |
| 46 | in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. | |
| 47 | in[1-4]_lcrit Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register. | |
| 48 | in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. | |
| 49 | in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. | |
| 50 | in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. | |
| 51 | in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. | |
| 52 | in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. | |
| 53 | ||
| 54 | temp1_input Measured temperature. From READ_TEMPERATURE_1 register. | |
| 55 | temp1_max Maximum temperature. From OT_WARN_LIMIT register. | |
| 56 | temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. | |
| 57 | temp1_max_alarm Chip temperature high alarm. Set by comparing | |
| 58 | READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING | |
| 59 | status is set. | |
| 60 | temp1_crit_alarm Chip temperature critical high alarm. Set by comparing | |
| 61 | READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT | |
| 62 | status is set. |
