Changes since RFC: *Moved the Temperature sensor driver from driver/hwmon/ to driver/mfd as discussed with Guenter Roeck <guenter.roeck@xxxxxxxxxxxx> and Donggeun Kim <dg77.kim@xxxxxxxxxxx> (https://lkml.org/lkml/2012/1/5/7) *Some changes according to the changes in common cpu cooling APIs All the patchset based on Kernel version 3.3-rc5 and uses the cpufreq cooling registration APIs implemented in earlier patchset https://lkml.org/lkml/2012/2/22/123 The code added in this patchset adds a thermal interface layer for samsung exynos platforms. This layer is registered from the temperature sensor driver 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. The future goal is to make this handle multiple thermal zones. 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 (4): thermal: exynos: Add thermal interface support for linux thermal layer hwmon: exynos4: Move thermal sensor driver to driver/mfd directory thermal: exynos4: Register the tmu sensor with the thermal interface layer ARM: exynos4: Add thermal sensor driver platform device support Documentation/hwmon/exynos4_tmu | 81 ----- Documentation/mfd/exynos4_tmu | 52 +++ arch/arm/mach-exynos/Kconfig | 11 + 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/Kconfig | 10 - drivers/hwmon/Makefile | 1 - drivers/hwmon/exynos4_tmu.c | 514 ----------------------------- drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 1 + drivers/mfd/exynos4_tmu.c | 443 +++++++++++++++++++++++++ drivers/thermal/Kconfig | 8 + drivers/thermal/Makefile | 1 + drivers/thermal/exynos_thermal.c | 272 +++++++++++++++ include/linux/exynos_thermal.h | 72 ++++ include/linux/platform_data/exynos4_tmu.h | 7 + 21 files changed, 951 insertions(+), 606 deletions(-) delete mode 100644 Documentation/hwmon/exynos4_tmu create mode 100644 Documentation/mfd/exynos4_tmu create mode 100644 arch/arm/mach-exynos/dev-tmu.c delete mode 100644 drivers/hwmon/exynos4_tmu.c create mode 100644 drivers/mfd/exynos4_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
