X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2cd29f6308b81fdf3756307c37bda267a93c1650;p=linux-beck.git

arm: dts: add cooling properties on omap5 cpu node

OMAP5 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.
