OMAP4430 devices can reach high temperatures and thus
needs to have cpufreq-cooling on systems running on it.

This patch adds the required cooling device properties
so that cpufreq-cpu0 driver loads the cooling device.

Alex, what's the status of this series? I could not find
the complete thread, so wondering what to do with patches
09 - 13?

Tony
