SPDX-License-Identifier: GPL-2.0-only + +Kernel driver mpq8785 +======================= + +Supported chips: + + * MPS MPQ8785 + + Prefix: 'mpq8785' + +Author: Charles Hsu <ythsu0511@gmail.com> + +Description +----------- + +The MPQ8785 is a fully integrated, PMBus-compatible, high-frequency, synchronous +buck converter. The MPQ8785 offers a very compact solution that achieves up to +40A output current per phase, with excellent load and line regulation over a +wide input supply range. The MPQ8785 operates at high efficiency over a wide +output current load range. + +The PMBus interface provides converter configurations and key parameters +monitoring. + +The MPQ8785 adopts MPS's proprietary multi-phase digital constant-on-time (MCOT) +control, which provides fast transient response and eases loop stabilization. +The MCOT scheme also allows multiple MPQ8785 devices to be connected in parallel +with excellent current sharing and phase interleaving for high-current +applications. + +Fully integrated protection features include over-current protection (OCP), +over-voltage protection (OVP), under-voltage protection (UVP), and +over-temperature protection (OTP). + +The MPQ8785 requires a minimal number of readily available, standard external +components, and is available in a TLGA (5mmx6mm) package. + +Device compliant with: + +- PMBus rev 1.3 interface. + +The driver exports the following attributes via the 'sysfs' files +for input voltage: + +**in1_input** + +**in1_label** + +**in1_max** + +**in1_max_alarm** + +**in1_min** + +**in1_min_alarm** + +**in1_crit** + +**in1_crit_alarm** + +The driver provides the following attributes for output voltage: + +**in2_input** + +**in2_label** + +**in2_alarm** + +The driver provides the following attributes for output current: + +**curr1_input** + +**curr1_label** + +**curr1_max** + +**curr1_max_alarm** + +**curr1_crit** + +**curr1_crit_alarm** + +The driver provides the following attributes for temperature: + +**temp1_input** + +**temp1_max** + +**temp1_max_alarm** + +**temp1_crit** + +**temp1_crit_alarm** |
