 20Description
 21-----------
 22
 23This driver implements support for TI TPS25990 eFuse.
 24This is an integrated, high-current circuit protection and power
 25management device with PMBUS interface
 26
 27Device compliant with:
 28
 29- PMBus rev 1.3 interface.
 30
 31Device supports direct format for reading input voltages,
 32output voltage, input current, input power and temperature.
 33
 34Due to the specificities of the chip, all history reset attributes
 35are tied together. Resetting the history of a sensor, resets the
 36history of all the sensors.
 37
 38The driver exports the following attributes via the 'sysfs' files
 39for input current:
 40
 41**curr1_average**
 42
 43**curr1_crit**
 44
 45**curr1_crit_alarm**
