Subject: [RFC PATCH 0/3] thermal: exynos: Add kernel thermal support for exynos platform
Date: Wed, 21 Dec 2011 17:29:55 +0530 [thread overview]
Message-ID: <1324468798-20423-1-git-send-email-amit.kachhap@linaro.org> (raw)
All the patchset based on Kernel version 3.2-rc6 and uses the cpufreq
cooling registration api's implemented in earlier patchset
http://www.spinics.net/lists/linux-pm/msg26500.html
The code added in this patchset adds a thermal interface layer for samsung
exynos platforms. This layer is registered from the hwmon based temperature
sensor 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.
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
