This patch adds the TMU (Thermal Management Unit) sensor devicetree node for Exynos5433. 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 <kgene@kernel.org> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Inki Dae <inki.dae@samsung.com> Reviewed-by: Lukasz Majewski <redacted> --- .../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
