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