They also feature current and voltage readback via an -integrated 12 bit analog-to-digital converter (ADC), accessed using a -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. - -The ADM1075, unlike many other PMBus devices, does not support internal voltage -or current scaling. Reported voltages, currents, and power are raw measurements, -and will typically have to be scaled. - -The shunt value in micro-ohms can be set via device tree at compile-time. Please -refer to the Documentation/devicetree/bindings/hwmon/adm1275.txt for bindings -if the device tree is used. - -Platform data support ---------------------- - -The driver supports standard PMBus driver platform data. Please see -Documentation/hwmon/pmbus for details. - - -Sysfs entries -------------- - -The following attributes are supported. Limits are read-write, history reset -attributes are write-only, all other attributes are read-only. - -inX_label "vin1" or "vout1" depending on chip variant and - configuration. On ADM1075, ADM1293, and ADM1294, - vout1 reports the voltage on the VAUX pin. -inX_input Measured voltage. -inX_min Minimum Voltage. -inX_max Maximum voltage. -inX_min_alarm Voltage low alarm. -inX_max_alarm Voltage high alarm. -inX_highest Historical maximum voltage. -inX_reset_history Write any value to reset history. - -curr1_label "iout1" -curr1_input Measured current. -curr1_max Maximum current. -curr1_max_alarm Current high alarm. -curr1_lcrit Critical minimum current. Depending on the chip - configuration, either curr1_lcrit or curr1_crit is - supported, but not both. -curr1_lcrit_alarm Critical current low alarm. -curr1_crit Critical maximum current. Depending on the chip - configuration, either curr1_lcrit or curr1_crit is - supported, but not both. -curr1_crit_alarm Critical current high alarm. -curr1_highest Historical maximum current. -curr1_reset_history Write any value to reset history. - -power1_label "pin1" -power1_input Input power. -power1_input_lowest Lowest observed input power. ADM1293 and ADM1294 only. -power1_input_highest Highest observed input power. -power1_reset_history Write any value to reset history. - - Power attributes are supported on ADM1075, ADM1272, - ADM1276, ADM1293, and ADM1294. - -temp1_input Chip temperature. -temp1_max Maximum chip temperature. -temp1_max_alarm Temperature alarm. -temp1_crit Critical chip temperature. -temp1_crit_alarm Critical temperature high alarm. -temp1_highest Highest observed temperature. -temp1_reset_history Write any value to reset history. - - Temperature attributes are supported on ADM1272 and - ADM1278. |
