This patch add the cooling device to control the overheating issue on Exynos3250-based Rinato/Monk board.
Cc: Kukjin Kim <[email protected]> Cc: Krzysztof Kozlowski <[email protected]> Signed-off-by: Chanwoo Choi <[email protected]> Acked-by: Kyungmin Park <[email protected]> --- Depends on: This patch needs the cpufreq support of Exynos3250 SoC. So, this patch has the dependency on patch[1] which support the generic cpufreq for Exynos3250 SoC.
