ARM: dts: exynos: Add CPU cooling in SMDKv310
Add missing cooling devices for CPU thermal zones in Exynos4210 SMDKv310 board. This allows to scale down CPU frequency (and voltage) in case of thermal pressure. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200830135200.24304-20-krzk@kernel.org
