Subject[PATCH 4.18 044/228] ARM: dts: ls1021a: Add missing cooling device properties for CPUs
4.18-stable review patch.  If anyone has any objections, please let me know.


From: Viresh Kumar <>

[ Upstream commit 47768f372eae030db6fab5225f9504a820d2c07f ]

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.
