All the patchset based on Kernel version 3.2-rc6 and uses the cpufreq cooling registration api's implemented in earlier patchset http://www.spinics.net/lists/linux-pm/msg26500.html The code added in this patchset adds a thermal interface layer for samsung exynos platforms. This layer is registered from the hwmon based temperature sensor and recieves/monitor the temperature from the sensor and informs the generic thermal layer to take the necessary cooling action. Currently this layer can be used to create only one thermal zone and hence only one temperature sensor can register. Some modifications are done in the temperature sensor driver to export the information needed for the thermal interface to register with the core linux thermal framework and with the cpu frequency based cooling devices. A simple data/control flow diagrams to illustrate this, Core Linux thermal <-------> Exynos thermal <-------- Temperature Sensor | | \|/ | Cpufreq cooling device <----- Amit Daniel Kachhap (3): thermal: exynos: Add thermal interface support for linux thermal layer thermal: exynos4: Register the tmu sensor with the thermal interface layer ARM: exynos4: Add thermal sensor driver platform device support arch/arm/mach-exynos/Kconfig | 12 ++ arch/arm/mach-exynos/Makefile | 1 + arch/arm/mach-exynos/clock.c | 4 + arch/arm/mach-exynos/dev-tmu.c | 64 +++++++ arch/arm/mach-exynos/include/mach/irqs.h | 2 + arch/arm/mach-exynos/include/mach/map.h | 1 + arch/arm/mach-exynos/mach-origen.c | 1 + arch/arm/plat-samsung/include/plat/devs.h | 1 + drivers/hwmon/exynos4_tmu.c | 34 ++++- drivers/thermal/Kconfig | 8 + drivers/thermal/Makefile | 1 + drivers/thermal/exynos_thermal.c | 255 +++++++++++++++++++++++++++++ include/linux/exynos_thermal.h | 59 +++++++ include/linux/platform_data/exynos4_tmu.h | 7 + 14 files changed, 447 insertions(+), 3 deletions(-) create mode 100644 arch/arm/mach-exynos/dev-tmu.c create mode 100644 drivers/thermal/exynos_thermal.c create mode 100644 include/linux/exynos_thermal.h _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/linux-pm
