    Subject[PATCH 0/4] thermal: exynos: Add kernel thermal support for exynos platform
    Date
    Changes since RFC:
    *Moved the Temperature sensor driver from driver/hwmon/ to driver/mfd
    as discussed with Guenter Roeck <guenter.roeck@ericsson.com> and
    Donggeun Kim <dg77.kim@samsung.com> (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
