Re: [PATCH 06/15] arm: dts: sun: Add missing cooling device properties for CPUs

Hi,

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, OPP, clock latency) as well to
make it all work.

The prefix should be sunxi and not sun, but it looks good to me
otherwise.

Let me know what your preferred merge method is.
