From mboxrd@z Thu Jan 1 00:00:00 1970 From: Viresh Kumar Subject: [PATCH 02/15] arm: dts: ls1021a: Add missing cooling device properties for CPUs Date: Fri, 25 May 2018 16:01:48 +0530 Message-ID: References: Return-path: In-Reply-To: In-Reply-To: References: Sender: linux-kernel-owner@vger.kernel.org To: arm@kernel.org, Rob Herring , Mark Rutland Cc: Viresh Kumar , Vincent Guittot , ionela.voinescu@arm.com, Daniel Lezcano , chris.redpath@arm.com, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.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.
