From 1e4063329fe865380177945efed3a42c0bbbfa05 Mon Sep 17 00:00:00 2001 From: Erik Rosen Date: Mon, 19 Apr 2021 12:12:51 +0200 Subject: hwmon: (pmbus) Add pmbus driver for MAX15301 Add pmbus driver support for Maxim MAX15301 InTune Automatically Compensated Digital PoL Controller with Driver and PMBus Telemetry Even though the specification does not specifically mention it, extensive empirical testing has revealed that auto-detection of limit-registers will fail in a random fashion unless the delay parameter is set to above about 80us. The default delay is set to 100us to include some safety margin. This patch is tested on a Flex BMR461 converter module.
