This patchset introduces a new generic cooling device based on cpufreq that
can be used on non-ACPI platforms. As a proof of concept, we have drivers for
the following platforms using this mechanism now:

 * TI OMAP (git://git.linaro.org/people/amitdanielk/linux.git omap4460_thermal)
 * Samsung Exynos (Exynos4 and Exynos5) in the current patchset.
 * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal)

These patches have been reviewed by Rui Zhang (https://lkml.org/lkml/2012/4/9/448)

But we don't have explicit Reviewed-by:s for the changelogs?

who seems to agree with them in principle, but I haven't had any luck getting them
merged, perhaps a lack of maintainer bandwidth.

ACPI platforms currently have such a mechanism but it is wrapped in ACPI'isms
that we don't have on ARM platforms. If this is accepted, I'm proposing to
convert over the ACPI thermal driver to use this common code too.
