- Kernel driver max8688
- =====================
- Supported chips:
- * Maxim MAX8688
- Prefix: 'max8688'
- Addresses scanned: -
- Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX8688.pdf
- Author: Guenter Roeck <linux@roeck-us.net>
- 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.
