Subject[PATCHv5 00/10] Thermal Framework Enhancements
Date
This patch set is a v5 of the previous versions submitted here:
[v4]: http://lwn.net/Articles/568988/
[v3]: https://lkml.org/lkml/2013/2/5/228
[v2]: http://lwn.net/Articles/531720/
[v1]: https://lkml.org/lkml/2012/12/18/108
[RFC]:https://patchwork.kernel.org/patch/1758921/

This patch set is based on Rui's -next tree, on top
of commit 'c698a4492f01127ca90fc28cd5157f3d616fe4ff'
This is tested on a Core-i5 running ubuntu 12.04.

Changes since v4:
* Cleaned up the thermal_release function; Now all
kfree's are done in _unregister functions.
* Kconfig option to selectively enable and use this
new version of thermal_core.c
* According to a previous comment from Rui, moved all
new API's into a file named thermal_core_new.c
Changes since v3:
* Added a patch to conditionally do kfree(cdev) in
thermal_release function.
* Reworked all sysfs attributes to have one value per file
This includes sensor_trip_* and map_weight* attributes.
* Added 'lock' variable in thermal_zone structure to
protect its members.
* Added Documentation to all functions in thermal_core.c
* Changes all strcpy() to strlcpy()
* Used devm_kzalloc() in places where applicable
* Address some buffer overflow conditions and contentions
in tz->sensors[] and tz->cdevs[].
Changes since v2:
* Reworked the map sysfs attributes in patch [5/8]
* Dropped configuration for maximum sensors and
cooling devices, through Kconfig.
* Added __remove_trip_attr method
* Renamed __clean_map_entry to __remove_map_entry
for consistency in naming.
Changes Since v1:
* Removed kobject creation for thermal_trip and thermal_map
nodes as per Greg-KH's comments.
* Added ABI Documentation under 'testing'.
* Modified the GET_INDEX macro to be more linux-like, thanks
to Joe Perches.
* Added get_[sensor/cdev]_by_name APIs to thermal.h

This series contains 10 patches:
Patch 1/10: Remove code from thermal_release function.
Do kfree in _unregister functions.
Patch 2/10: Creates new sensor level APIs
Patch 3/10: Adds new cooling device APIs
Patch 4/10: Creates new zone level APIs. The existing tzd structure is
kept as such for clarity and compatibility purposes.
Patch 5/10: Creates functions to add/remove a cdev to/from a zone. The
existing tcd structure need not be modified.
Patch 6/10: Adds sensorX_trip_[active/passive/hot/critical] sysfs nodes,
under /sys/class/thermal/zoneY/. This exposes various trip
points for sensorX present in zoneY.
Patch 7/10: Adds mapY_* sysfs node. These attributes represent the
relationship between various sensors and cooling
devices in a thermal zone.
Patch 8/10: Creates Documentation for the new APIs. A new file is
created for clarity. Final goal is to merge with the existing
file or refactor the files, as whatever seems appropriate.
Patch 9/10: Add ABI documentation for sysfs interfaces introduced in this patch.
Patch 10/10: A dummy driver that can be used for testing. This is not for merge.

Thanks to Rui for helping me in resolving some
Kconfig issues, related to this series.
