Subject: [PATCH 1/3] docs: hwmon: Add attributes to report rated values
Date: Fri, 31 Jul 2020 21:37:15 +0200
Message-ID: <1596224237-32280-2-git-send-email-zbigniew.lukwinski@linux.intel.com> (raw)
In-Reply-To: <1596224237-32280-1-git-send-email-zbigniew.lukwinski@linux.intel.com>

New attributes (rated_min/rated_max) are being added the hwmon ABI.
They are needed to cover rated values documented by PMBus
specification:
PMBus Power System Mgt Protocol Specification - Part II – Revision 1.3.1,
chapters: 22.3.1 - 22.3.10, 22.3.15
