Please see 42 Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 43 44 45 Usage Notes 46 ----------- 47 48 This driver does not auto-detect devices. You will have to instantiate the 49 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for 50 details. 51 52 Example: the following will load the driver for an PFE3000 at address 0x20 53 on I2C bus #1:: 54 55 $ modprobe bel-pfe 56 $ echo pfe3000 0x20 > /sys/bus/i2c/devices/i2c-1/new_device 57 58 59 Platform data support 60 --------------------- 61 62 The driver supports standard PMBus driver platform data. 63 64 65 Sysfs entries 66 ------------- 67 68 ======================= ======================================================= 69 curr1_label "iin" 70 curr1_input Measured input current 71 curr1_max Input current max value 72 curr1_max_alarm Input current max alarm 73 74 curr[2-3]_label "iout[1-2]" 75 curr[2-3]_input Measured output current 76 curr[2-3]_max Output current max value 77 curr[2-3]_max_alarm Output current max alarm 78 79 fan[1-2]_input Fan 1 and 2 speed in RPM 80 fan1_target Set fan speed reference for both fans 81 82 in1_label "vin" 83 in1_input Measured input voltage 84 in1_crit Input voltage critical max value 85 in1_crit_alarm Input voltage critical max alarm 86 in1_lcrit Input voltage critical min value 87 in1_lcrit_alarm Input voltage critical min alarm 88 in1_max Input voltage max value 89 in1_max_alarm Input voltage max alarm 90 91 in2_label "vcap" 92 in2_input Hold up capacitor voltage 93 94 in[3-8]_label "vout[1-3,5-7]" 95 in[3-8]_input Measured output voltage 96 in[3-4]_alarm vout[1-2] output voltage alarm 97 98 power[1-2]_label "pin[1-2]" 99 power[1-2]_input Measured input power 100 power[1-2]_alarm Input power high alarm 101 102 power[3-4]_label "pout[1-2]" 103 power[3-4]_input Measured output power 104 105 temp[1-3]_input Measured temperature 106 temp[1-3]_alarm Temperature alarm 107 ======================= ======================================================= 108 109 .. note:: 110 111 - curr3, fan2, vout[2-7], vcap, pin2, pout2 and temp3 attributes only 112 exist for PFE3000.
