68 This driver supports hardware monitoring for Analog Devices ADM1075, ADM1272,
69 ADM1275, ADM1276, ADM1278, ADM1281, ADM1293, and ADM1294 Hot-Swap Controller and
70 Digital Power Monitors.
72 ADM1075, ADM1272, ADM1275, ADM1276, ADM1278, ADM1281, ADM1293, and ADM1294 are hot-swap
73 controllers that allow a circuit board to be removed from or inserted into
74 a live backplane. They also feature current and voltage readback via an
75 integrated 12 bit analog-to-digital converter (ADC), accessed using a
78 The driver is a client driver to the core PMBus driver. Please see
79 Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
85 This driver does not auto-detect devices. You will have to instantiate the
86 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
89 The ADM1075, unlike many other PMBus devices, does not support internal voltage
90 or current scaling. Reported voltages, currents, and power are raw measurements,
91 and will typically have to be scaled.
93 The shunt value in micro-ohms can be set via device tree at compile-time. Please
94 refer to the Documentation/devicetree/bindings/hwmon/adi,adm1275.yaml for bindings
95 if the device tree is used.
100 The driver supports standard PMBus driver platform data. Please see
101 Documentation/hwmon/pmbus.rst for details.
107 The following attributes are supported. Limits are read-write, history reset
108 attributes are write-only, all other attributes are read-only.
110 ======================= =======================================================
111 inX_label "vin1" or "vout1" depending on chip variant and
112 configuration. On ADM1075, ADM1293, and ADM1294,
113 vout1 reports the voltage on the VAUX pin.
114 inX_input Measured voltage.
115 inX_min Minimum Voltage.
116 inX_max Maximum voltage.
117 inX_min_alarm Voltage low alarm.
118 inX_max_alarm Voltage high alarm.
119 inX_highest Historical maximum voltage.
120 inX_reset_history Write any value to reset history.
123 curr1_input Measured current.
124 curr1_max Maximum current.
125 curr1_max_alarm Current high alarm.
126 curr1_lcrit Critical minimum current. Depending on the chip
127 configuration, either curr1_lcrit or curr1_crit is
128 supported, but not both.
129 curr1_lcrit_alarm Critical current low alarm.
130 curr1_crit Critical maximum current. Depending on the chip
131 configuration, either curr1_lcrit or curr1_crit is
132 supported, but not both.
133 curr1_crit_alarm Critical current high alarm.
134 curr1_highest Historical maximum current.
135 curr1_reset_history Write any value to reset history.
138 power1_input Input power.
139 power1_input_lowest Lowest observed input power. ADM1293 and ADM1294 only.
140 power1_input_highest Highest observed input power.
141 power1_reset_history Write any value to reset history.
143 Power attributes are supported on ADM1075, ADM1272,
144 ADM1276, ADM1293, and ADM1294.
146 temp1_input Chip temperature.
147 temp1_max Maximum chip temperature.
148 temp1_max_alarm Temperature alarm.
149 temp1_crit Critical chip temperature.
150 temp1_crit_alarm Critical temperature high alarm.
151 temp1_highest Highest observed temperature.
152 temp1_reset_history Write any value to reset history.
154 Temperature attributes are supported on ADM1272 and
155 ADM1278, and ADM1281.
