It uses already present thermal infrastructure to provide boost hysteresis. The TMU data has been modified to work properly with or without boost. Signed-off-by: Lukasz Majewski Signed-off-by: Myungjoo Ham Acked-by: Eduardo Valentin --- Changes for v11: - Use only one thermal data set - Adjust Exynos4412 thermal data to work with or without BOOST Changes for v10: - Remove boost related code from thermal_core.c - Use already present thermal infrastructure to provide thermal hysteresis - Introduce special set of TMU data for BOOST Changes for v9: - None Changes for v8: - Move cpufreq_boost_* stub functions definition (needed when cpufreq is not compiled in) to cpufreq.h at cpufreq core support commit Changes for v7: - None Changes for v6: - Disable boost only when supported and enabled - Protect boost related thermal_zone_device struct fields with mutex - Evaluate temperature trend during boost enable decision - Create separate methods to handle boost enable/disable (thermal_boost_{enable|disable}) operations - Boost is disabled at any trip point passage (not only the non critical one) - Add stub definitions for cpufreq boost functions used when CONFIG_CPU_FREQ is NOT defined. Changes for v5: - Move boost disable code from cpu_cooling.c to thermal_core.c (to handle_non_critical_trips) - Extent struct thermal_zone_device by adding overheated bool flag - Implement auto enable of boost after device cools down - Introduce boost_polling flag, which indicates if thermal uses it's predefined pool delay or has woken up thermal workqueue only to wait until device cools down.
