20 This driver supports TI TPS40422 Dual-Output or Two-Phase Synchronous Buck
23 The driver is a client driver to the core PMBus driver.
24 Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
30 This driver does not auto-detect devices. You will have to instantiate the
31 devices explicitly. Please see Documentation/i2c/instantiating-devices for
38 The driver supports standard PMBus driver platform data.
44 The following attributes are supported.
46 ======================= =======================================================
47 in[1-2]_label "vout[1-2]"
48 in[1-2]_input Measured voltage. From READ_VOUT register.
49 in[1-2]_alarm voltage alarm.
51 curr[1-2]_input Measured current. From READ_IOUT register.
52 curr[1-2]_label "iout[1-2]"
53 curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
54 curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT
56 curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT status.
57 curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status.
58 curr2_alarm Current high alarm. From IOUT_OC_WARNING status.
60 temp1_input Measured temperature. From READ_TEMPERATURE_2 register
62 temp1_max Maximum temperature. From OT_WARN_LIMIT register.
63 temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
64 temp1_max_alarm Chip temperature high alarm. Set by comparing
65 READ_TEMPERATURE_2 on page 0 with OT_WARN_LIMIT if
66 TEMP_OT_WARNING status is set.
67 temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
68 READ_TEMPERATURE_2 on page 0 with OT_FAULT_LIMIT if
69 TEMP_OT_FAULT status is set.
70 temp2_input Measured temperature. From READ_TEMPERATURE_2 register
72 temp2_alarm Chip temperature alarm on page 1.
