BTW unfortunately, since missing the "include/dt-bindings/thermal/thermal_exynos.h" in my tree, I couldn't merge it into for-next yet. Can you please provide a topic branch for it? If not, this cannot be handled in arm-soc tree in this time, I think. - Kukjin > > Thanks a lot. > >> >> .../devicetree/bindings/thermal/exynos-thermal.txt | 17 + >> arch/arm/boot/dts/exynos3250.dtsi | 2 + >> arch/arm/boot/dts/exynos4-cpu-thermal.dtsi | 52 +++ >> arch/arm/boot/dts/exynos4.dtsi | 4 + >> arch/arm/boot/dts/exynos4210-trats.dts | 19 + >> arch/arm/boot/dts/exynos4210.dtsi | 30 +- >> arch/arm/boot/dts/exynos4212.dtsi | 5 +- >> arch/arm/boot/dts/exynos4412-odroid-common.dtsi | 27 ++ >> arch/arm/boot/dts/exynos4412-tmu-sensor-conf.dtsi | 24 ++ >> arch/arm/boot/dts/exynos4412-trats2.dts | 15 + >> arch/arm/boot/dts/exynos4412.dtsi | 5 +- >> arch/arm/boot/dts/exynos4x12.dtsi | 1 + >> arch/arm/boot/dts/exynos5250.dtsi | 29 +- >> arch/arm/boot/dts/exynos5420-trip-points.dtsi | 35 ++ >> arch/arm/boot/dts/exynos5420.dtsi | 28 ++ >> arch/arm/boot/dts/exynos5440-tmu-sensor-conf.dtsi | 24 ++ >> arch/arm/boot/dts/exynos5440-trip-points.dtsi | 25 ++ >> arch/arm/boot/dts/exynos5440.dtsi | 18 + >> drivers/cpufreq/exynos-cpufreq.c | 33 +- >> drivers/thermal/sam`sung/Makefile | 2 - >> drivers/thermal/samsung/exynos_thermal_common.c | 427 --------------------- >> drivers/thermal/samsung/exynos_thermal_common.h | 106 ----- >> drivers/thermal/samsung/exynos_tmu.c | 348 +++++++++++------ >> drivers/thermal/samsung/exynos_tmu.h | 76 +--- >> drivers/thermal/samsung/exynos_tmu_data.c | 264 ------------- >> include/dt-bindings/thermal/thermal_exynos.h | 28 ++ >> 26 files changed, 636 insertions(+), 1008 deletions(-) >> create mode 100644 arch/arm/boot/dts/exynos4-cpu-thermal.dtsi >> create mode 100644 arch/arm/boot/dts/exynos4412-tmu-sensor-conf.dtsi >> create mode 100644 arch/arm/boot/dts/exynos5420-trip-points.dtsi >> create mode 100644 arch/arm/boot/dts/exynos5440-tmu-sensor-conf.dtsi >> create mode 100644 arch/arm/boot/dts/exynos5440-trip-points.dtsi >> delete mode 100644 drivers/thermal/samsung/exynos_thermal_common.c >> delete mode 100644 drivers/thermal/samsung/exynos_thermal_common.h >> delete mode 100644 drivers/thermal/samsung/exynos_tmu_data.c >> create mode 100644 include/dt-bindings/thermal/thermal_exynos.h -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
