1 Kernel driver max8688 2 ===================== 3 4 Supported chips: 5 * Maxim MAX8688 6 Prefix: 'max8688' 7 Addresses scanned: - 8 Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX8688.pdf 9 10 Author: Guenter Roeck <linux@roeck-us.net> 11 12 13 Description 14 ----------- 15 16 This driver supports hardware monitoring for Maxim MAX8688 Digital Power-Supply 17 Controller/Monitor with PMBus Interface. 18 19 The driver is a client driver to the core PMBus driver. Please see 20 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 in1_label "vout1" 44 in1_input Measured voltage. From READ_VOUT register. 45 in1_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register. 46 in1_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. 47 in1_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register. 48 in1_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. 49 in1_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. 50 in1_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. 51 in1_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. 52 in1_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. 53 in1_highest Historical maximum voltage. 54 in1_reset_history Write any value to reset history. 55 56 curr1_label "iout1" 57 curr1_input Measured current. From READ_IOUT register. 58 curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register. 59 curr1_crit Critical maximum current.

From READ_TEMPERATURE_1 register. 66 temp1_max Maximum temperature. From OT_WARN_LIMIT register. 67 temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. 68 temp1_max_alarm Chip temperature high alarm. Set by comparing 69 READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING 70 status is set. 71 temp1_crit_alarm Chip temperature critical high alarm. Set by comparing 72 READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT 73 status is set. 74 temp1_highest Historical maximum temperature. 75 temp1_reset_history Write any value to reset history.
