ARM: dts: dra74x: 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. Fix other missing properties (clocks, supply, clock latency) as well to make it all work. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
