From mboxrd@z Thu Jan 1 00:00:00 1970 From: viresh.kumar@linaro.org (Viresh Kumar) Date: Fri, 25 May 2018 16:01:51 +0530 Subject: [PATCH 05/15] arm: dts: uniphier: Add missing cooling device properties for CPUs In-Reply-To: References: Message-ID: <51ac4a5f0466aeed3f223663d9c34d6345b2a1f2.1527244201.git.viresh.kumar@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.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.
