Arndale Octa board comes without fan so proper CPU cooling is necessary to avoid critical shutdowns when CPUs are busy. Although thermal zones were present but CPU cooling was missing in DTS. Adjust the trip points and add respective cooling nodes for each CPU thermal zone. The CPU throttling will start at 60 degrees of C, intensify at 80 degrees of C and slow down CPUs as much as possible at 110 degrees of C. With this configuration, when running four CPU intensive tasks, the temperatures did not exceed 90 degrees of Celsius mostly oscillating around 88 degrees in hottest thermal zone. Test was however done with only four CPUs online (big cluster, Cortex A15) because of errors when booting secondary CPUs. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> |
