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** |
