They also feature current and voltage readback via an 39 integrated 12 bit analog-to-digital converter (ADC), accessed using a 40 PMBus interface. 41 42 The driver is a client driver to the core PMBus driver. Please see 43 Documentation/hwmon/pmbus for details on PMBus client drivers. 44 45 46 Usage Notes 47 ----------- 48 49 This driver does not auto-detect devices. You will have to instantiate the 50 devices explicitly. Please see Documentation/i2c/instantiating-devices for 51 details. 52 53 The ADM1075, unlike many other PMBus devices, does not support internal voltage 54 or current scaling. Reported voltages, currents, and power are raw measurements, 55 and will typically have to be scaled. 56 57 58 Platform data support 59 --------------------- 60 61 The driver supports standard PMBus driver platform data. Please see 62 Documentation/hwmon/pmbus for details. 63 64 65 Sysfs entries 66 ------------- 67 68 The following attributes are supported. Limits are read-write, history reset 69 attributes are write-only, all other attributes are read-only. 70 71 inX_label "vin1" or "vout1" depending on chip variant and 72 configuration. On ADM1075, ADM1293, and ADM1294, 73 vout1 reports the voltage on the VAUX pin. 74 inX_input Measured voltage. 75 inX_min Minimum Voltage. 76 inX_max Maximum voltage. 77 inX_min_alarm Voltage low alarm. 78 inX_max_alarm Voltage high alarm. 79 inX_highest Historical maximum voltage. 80 inX_reset_history Write any value to reset history. 81 82 curr1_label "iout1" 83 curr1_input Measured current. 84 curr1_max Maximum current. 85 curr1_max_alarm Current high alarm. 86 curr1_lcrit Critical minimum current. Depending on the chip 87 configuration, either curr1_lcrit or curr1_crit is 88 supported, but not both. 89 curr1_lcrit_alarm Critical current low alarm. 90 curr1_crit Critical maximum current. Depending on the chip 91 configuration, either curr1_lcrit or curr1_crit is 92 supported, but not both. 93 curr1_crit_alarm Critical current high alarm. 94 curr1_highest Historical maximum current. 95 curr1_reset_history Write any value to reset history. 96 97 power1_label "pin1" 98 power1_input Input power. 99 power1_input_lowest Lowest observed input power. ADM1293 and ADM1294 only. 100 power1_input_highest Highest observed input power. 101 power1_reset_history Write any value to reset history. 102 103 Power attributes are supported on ADM1075, ADM1276, 104 ADM1293, and ADM1294. 105 106 temp1_input Chip temperature. 107 Temperature attributes are only available on ADM1278. 108 temp1_max Maximum chip temperature. 109 temp1_max_alarm Temperature alarm. 110 temp1_crit Critical chip temperature. 111 temp1_crit_alarm Critical temperature high alarm. 112 temp1_highest Highest observed temperature. 113 temp1_reset_history Write any value to reset history. 114 115 Temperature attributes are supported on ADM1278.
