From a7a6e2cbb4db370e84948e97adac332b59dd89d8 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 16 Nov 2018 15:34:27 +0530 Subject: arm64: dts: hi3660: Add missing cooling device properties for CPUs 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.
