Subject: [PATCH v2 3/3] dt-bindings: thermal: update sustainable-power with abstract scale
Date: Fri,  2 Oct 2020 12:44:26 +0100	[thread overview]
Message-ID: <20201002114426.31277-4-lukasz.luba@arm.com> (raw)
In-Reply-To: <20201002114426.31277-1-lukasz.luba@arm.com>

Update the documentation for the binding 'sustainable-power' and allow
to provide values in an abstract scale. It is required when the cooling
devices use an abstract scale for their power values.
