Subject: [PATCH 1/4] dt-bindings: opp: Introduce opp-sustainable bindings
Date: Wed, 28 Oct 2020 14:08:44 +0000	[thread overview]
Message-ID: <20201028140847.1018-2-lukasz.luba@arm.com> (raw)
In-Reply-To: <20201028140847.1018-1-lukasz.luba@arm.com>

Add opp-sustainable as an additional property in the OPP node to describe
the sustainable performance level of the device. This will help to
estimate the sustainable performance of the whole system.
