Subject[PATCH 10/19] arm: dts: add cooling properties on omap4430 cpu node
Date
From: Eduardo Valentin <eduardo.valentin@ti.com>

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.
