Subject: [PATCH 08/15] arm: dts: dra74x: Add missing cooling device properties for CPUs
Date: Fri, 25 May 2018 16:01:54 +0530 [thread overview]
Message-ID: <4860aab6e550b91ecc5c37c80cbffa6a6a70a4c9.1527244201.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1527244200.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1527244200.git.viresh.kumar@linaro.org>
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.
Fix other missing properties (clocks, supply, clock latency) as well to
make it all work.
