1Kernel driver max16064 2====================== 3 4Supported chips: 5 * Maxim MAX16064 6 Prefix: 'max16064' 7 Addresses scanned: - 8 Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX16064.pdf 9 10Author: Guenter Roeck <linux@roeck-us.net> 11 12 13Description 14----------- 15 16This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply 17Controller with Active-Voltage Output Control and PMBus Interface. 18 19The driver is a client driver to the core PMBus driver. 20Please see Documentation/hwmon/pmbus for details on PMBus client drivers. 21 22 23Usage Notes 24----------- 25 26This driver does not auto-detect devices. You will have to instantiate the 27devices explicitly. Please see Documentation/i2c/instantiating-devices for 28details. 29 30 31Platform data support 32--------------------- 33 34The driver supports standard PMBus driver platform data. 35 36 37Sysfs entries 38------------- 39 40The following attributes are supported. Limits are read-write; all other 41attributes are read-only. 42 43in[1-4]_label "vout[1-4]" 44in[1-4]_input Measured voltage. From READ_VOUT register. 45in[1-4]_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register. 46in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register. 47in[1-4]_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register. 48in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register. 49in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status. 50in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status. 51in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT status. 52in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT status. 53in[1-4]_highest Historical maximum voltage. 54in[1-4]_reset_history Write any value to reset history. 55 56temp1_input Measured temperature. From READ_TEMPERATURE_1 register. 57temp1_max Maximum temperature. From OT_WARN_LIMIT register. 58temp1_crit Critical high temperature. From OT_FAULT_LIMIT register. 59temp1_max_alarm Chip temperature high alarm. Set by comparing 60 READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING 61 status is set. 62temp1_crit_alarm Chip temperature critical high alarm. Set by comparing 63 READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT 64 status is set. 65temp1_highest Historical maximum temperature. 66temp1_reset_history Write any value to reset history. 67
