From a41ab6fe169943cfef516ee5230ba8ce55118112 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 25 May 2018 11:10:06 +0530 Subject: [PATCH] arm64: dts: uniphier: Add missing cooling device properties for CPUs [ Upstream commit af0e09d0c6762e486b0eb5cc4737396964c34fad ] 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.
