From 0bac06df36abb3b74e146091ca51c8c6d70d69a6 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 25 May 2018 16:01:50 +0530 Subject: [PATCH] ARM: dts: rockchip: Add missing cooling device properties for CPUs on rk322x 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.
