Please see 67 Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details 68 on PMBus client drivers. 69 70 71 Usage Notes 72 ----------- 73 74 This driver does not auto-detect devices. You will have to instantiate the 75 devices explicitly. Please see Documentation/i2c/instantiating-devices for 76 details. 77 78 WARNING: Do not access chip registers using the i2cdump command, and do not use 79 any of the i2ctools commands on a command register used to save and restore 80 configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by 81 this driver interpret any access to those command registers (including read 82 commands) as request to execute the command in question. Unless write accesses 83 to those registers are protected, this may result in power loss, board resets, 84 and/or Flash corruption. Worst case, your board may turn into a brick. 85 86 87 Platform data support 88 --------------------- 89 90 The driver supports standard PMBus driver platform data. 91 92 93 Module parameters 94 ----------------- 95 96 delay 97 ----- 98 99 Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C 100 bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms 101 appears to be sufficient and has not caused any problems in testing. The problem 102 is known to affect all currently supported chips. For manual override, the 103 driver provides a writeable module parameter, 'delay', which can be used to set 104 the interval to a value between 0 and 65,535 microseconds. 105 106 107 Sysfs entries 108 ------------- 109 110 The following attributes are supported. Limits are read-write; all other 111 attributes are read-only. 112 113 in1_label "vin" 114 in1_input Measured input voltage. 115 in1_min Minimum input voltage. 116 in1_max Maximum input voltage. 117 in1_lcrit Critical minimum input voltage. 118 in1_crit Critical maximum input voltage. 119 in1_min_alarm Input voltage low alarm. 120 in1_max_alarm Input voltage high alarm. 121 in1_lcrit_alarm Input voltage critical low alarm. 122 in1_crit_alarm Input voltage critical high alarm. 123 124 in2_label "vmon" 125 in2_input Measured voltage on VMON (ZL2004) or VDRV (ZL9101M, 126 ZL9117M) pin. Reported voltage is 16x the voltage on the 127 pin (adjusted internally by the chip). 128 in2_lcrit Critical minimum VMON/VDRV Voltage. 129 in2_crit Critical maximum VMON/VDRV voltage. 130 in2_lcrit_alarm VMON/VDRV voltage critical low alarm. 131 in2_crit_alarm VMON/VDRV voltage critical high alarm. 132 133 vmon attributes are supported on ZL2004, ZL9101M, 134 and ZL9117M only. 135 136 inX_label "vout1" 137 inX_input Measured output voltage. 138 inX_lcrit Critical minimum output Voltage. 139 inX_crit Critical maximum output voltage. 140 inX_lcrit_alarm Critical output voltage critical low alarm. 141 inX_crit_alarm Critical output voltage critical high alarm. 142 143 X is 3 for ZL2004, ZL9101M, and ZL9117M, 2 otherwise. 144 145 curr1_label "iout1" 146 curr1_input Measured output current. 147 curr1_lcrit Critical minimum output current. 148 curr1_crit Critical maximum output current. 149 curr1_lcrit_alarm Output current critical low alarm. 150 curr1_crit_alarm Output current critical high alarm. 151 152 temp[12]_input Measured temperature. 153 temp[12]_min Minimum temperature. 154 temp[12]_max Maximum temperature. 155 temp[12]_lcrit Critical low temperature. 156 temp[12]_crit Critical high temperature. 157 temp[12]_min_alarm Chip temperature low alarm. 158 temp[12]_max_alarm Chip temperature high alarm. 159 temp[12]_lcrit_alarm Chip temperature critical low alarm. 160 temp[12]_crit_alarm Chip temperature critical high alarm.
