Subject: [PATCH 1/6] arm64: dts: amlogic: Add missing cooling device properties for CPUs
Date:   Fri, 25 May 2018 11:10:01 +0530
Message-Id: <2a2eb28da9fecf129f6bc0ab3d3748d9f4d25a29.1527225682.git.viresh.kumar@linaro.org>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.
