The Exynos5433 includes the five temperature sensors as following: - two temperature sensor for Cortex-A57 (ATLAS) - one temperature sensor for Cortex-A53 (APOLLO) - one temperature sensor for G3D IP - one temperature sensor for ISP IP Cc: Kukjin Kim Signed-off-by: Chanwoo Choi Acked-by: Inki Dae Reviewed-by: Lukasz Majewski --- .../dts/exynos/exynos5433-tmu-sensor-conf.dtsi | 22 +++++++++ arch/arm64/boot/dts/exynos/exynos5433.dtsi | 55 ++++++++++++++++++++++ 2 files changed, 77 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos5433-tmu-sensor-conf.dtsi diff --git a/arch/arm64/boot/dts/exynos/exynos5433-tmu-sensor-conf.dtsi b/arch/arm64/boot/dts/exynos/exynos5433-tmu-sensor-conf.dtsi new file mode 100644 index 0000000..396e60f --- /dev/null +++ b/arch/arm64/boot/dts/exynos/exynos5433-tmu-sensor-conf.dtsi @@ -0,0 +1,22 @@ +/* + * Device tree sources for Exynos5433 TMU sensor configuration + * + * Copyright (c) 2015 Chanwoo Choi + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#include + +#thermal-sensor-cells = <0>; +samsung,tmu_gain = <8>; +samsung,tmu_reference_voltage = <16>; +samsung,tmu_noise_cancel_mode = <4>; +samsung,tmu_efuse_value = <75>; +samsung,tmu_min_efuse_value = <40>; +samsung,tmu_max_efuse_value = <150>; +samsung,tmu_first_point_trim = <25>; +samsung,tmu_second_point_trim = <85>; +samsung,tmu_default_temp_offset = <50>; diff --git a/arch/arm64/boot/dts/exynos/exynos5433.dtsi b/arch/arm64/boot/dts/exynos/exynos5433.dtsi index 5b80eb8..bde9cba 100644 --- a/arch/arm64/boot/dts/exynos/exynos5433.dtsi +++ b/arch/arm64/boot/dts/exynos/exynos5433.dtsi @@ -836,6 +836,61 @@ status = "disabled"; }; + tmu_atlas0: tmu at 10060000 { + compatible = "samsung,exynos5433-tmu"; + reg = <0x10060000 0x200>; + interrupts = <0 95 0>; + clocks = <&cmu_peris CLK_PCLK_TMU0_APBIF>, + <&cmu_peris CLK_SCLK_TMU0>; + clock-names = "tmu_apbif", "tmu_sclk"; + #include "exynos5433-tmu-sensor-conf.dtsi" + status = "disabled"; + }; + + tmu_atlas1: tmu at 10068000 { + compatible = "samsung,exynos5433-tmu"; + reg = <0x10068000 0x200>; + interrupts = <0 96 0>; + clocks = <&cmu_peris CLK_PCLK_TMU0_APBIF>, + <&cmu_peris CLK_SCLK_TMU0>; + clock-names = "tmu_apbif", "tmu_sclk"; + #include "exynos5433-tmu-sensor-conf.dtsi" + status = "disabled"; + }; + + tmu_g3d: tmu at 10070000 { + compatible = "samsung,exynos5433-tmu"; + reg = <0x10070000 0x200>; + interrupts = <0 99 0>; + clocks = <&cmu_peris CLK_PCLK_TMU1_APBIF>, + <&cmu_peris CLK_SCLK_TMU1>; + clock-names = "tmu_apbif", "tmu_sclk"; + #include "exynos5433-tmu-sensor-conf.dtsi" + status = "disabled"; + }; + + tmu_apollo: tmu at 10078000 { + compatible = "samsung,exynos5433-tmu"; + reg = <0x10078000 0x200>; + interrupts = <0 115 0>; + clocks = <&cmu_peris CLK_PCLK_TMU1_APBIF>, + <&cmu_peris CLK_SCLK_TMU1>; + clock-names = "tmu_apbif", "tmu_sclk"; + #include "exynos5433-tmu-sensor-conf.dtsi" + status = "disabled"; + }; + + tmu_isp: tmu at 1007c000 { + compatible = "samsung,exynos5433-tmu"; + reg = <0x1007c000 0x200>; + interrupts = <0 94 0>; + clocks = <&cmu_peris CLK_PCLK_TMU1_APBIF>, + <&cmu_peris CLK_SCLK_TMU1>; + clock-names = "tmu_apbif", "tmu_sclk"; + #include "exynos5433-tmu-sensor-conf.dtsi" + status = "disabled"; + }; + pmu_system_controller: system-controller at 105c0000 { compatible = "samsung,exynos5433-pmu", "syscon"; reg = <0x105c0000 0x5008>; -- 1.8.5.5
