It seems that Samsung is quite interested in pushing upstream Linux kernel support for their ARM-based Exynos 4210 SoC. Besides pushing an open-source DRM kernel graphics driver, they have been working on other areas of upstream Linux kernel support for this SoC that employs a dual-core Cortex A9.
Hitting the mailing list overnight (this time it's LM_Sensors) is the latest revision of a new driver that is for the Exynos 4-series TMU. This driver for the Samsung Exynos Thermal Management Unit (TMU) allows the SoC temperature to be exposed via conventional means with LM_Sensors. This work, like the Exynos 4210 DRM, was done officially by Samsung engineers.
