SPDX-License-Identifier: GPL-2.0 Kernel driver tps25990 ====================== Supported chips: * TI TPS25990 Prefix: 'tps25990' * Datasheet Publicly available at Texas Instruments website: https://www.ti.com/lit/gpn/tps25990 Author: Jerome Brunet Description ----------- This driver implements support for TI TPS25990 eFuse. This is an integrated, high-current circuit protection and power management device with PMBUS interface Device compliant with: - PMBus rev 1.3 interface. Device supports direct format for reading input voltages, output voltage, input current, input power and temperature. Due to the specificities of the chip, all history reset attributes are tied together. Resetting the history of a sensor, resets the history of all the sensors. The driver exports the following attributes via the 'sysfs' files for input current: **curr1_average** **curr1_crit** **curr1_crit_alarm** **curr1_highest** **curr1_input** **curr1_label** **curr1_max** **curr1_max_alarm** **curr1_reset_history** The driver provides the following attributes for main input voltage: **in1_average** **in1_crit** **in1_crit_alarm** **in1_highest** **in1_input** **in1_label** **in1_lcrit** **in1_lcrit_alarm** **in1_lowest** **in1_max** **in1_max_alarm** **in1_min** **in1_min_alarm** **in1_reset_history** The driver provides the following attributes for auxiliary input voltage: **in2_input** **in2_label** The driver provides the following attributes for output voltage: **in3_average** **in3_input** **in3_label** **in3_lowest** **in3_min** **in3_min_alarm** **in3_reset_history** The driver provides the following attributes for input power: **power1_alarm** **power1_average** **power1_input** **power1_input_highest** **power1_label** **power1_max** **power1_reset_history** The driver provides the following attributes for temperature: **temp1_average** **temp1_crit** **temp1_crit_alarm** **temp1_highest** **temp1_input** **temp1_max** **temp1_max_alarm** **temp1_reset_history** The driver provides the following attributes for sampling: **samples**
