| 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. |

| 31 | Platform data support |
| 32 | --------------------- |
| 33 | |
| 34 | The driver supports standard PMBus driver platform data. |

| 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. |
