Subject[PATCH 19/33] ARM: dts: exynos: Add CPU cooling in Origen
Date
Add missing cooling devices for CPU thermal zones in Exynos4210 Origen
board. This allows to scale down CPU frequency (and voltage) in case of
thermal pressure.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Not tested on HW.
