From 1967f712677429f52ac3e8896b5ecfecc2372d95 Mon Sep 17 00:00:00 2001 From: Zbigniew Lukwinski Date: Fri, 31 Jul 2020 21:37:16 +0200 Subject: [PATCH] hwmon: (core) Add support for rated attributes Adding implementation for new attributes (rated_min/rated_max) for currentX, inX, powerX, tempX and humidityX. Tested with OpenBMC stack and simple hwmon driver using rated_min/rated_max for the following types of sensors: hwmon_temp, hwmon_in, hwmon_curr, hwmon_power, hwmon_humidity. For each sensor rated attributes were available and returned expected values.
