2012-07-24Thermal: Make Thermal trip points writeableDurgadoss R
Some of the thermal drivers using the Generic Thermal Framework require (all/some) trip points to be writeable. This patch makes the trip point temperatures writeable on a per-trip point basis, and modifies the required function call in thermal.c. This patch also updates the Documentation to reflect the new change.

2012-01-23thermal: Rename generate_netlink_eventJean Delvare
It doesn't seem right for the thermal subsystem to export a symbol named generate_netlink_event. This function is thermal-specific and its name should reflect that fact. Rename it to thermal_generate_netlink_event. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Rafael J.

2011-01-12thermal: Add event notification to thermal frameworkR.Durgadoss
This patch adds event notification support to the generic thermal sysfs framework in the kernel. The notification is in the form of a netlink event. Signed-off-by: R.Durgadoss <durgadoss.r@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-11-05thermal: add sanity check for the passive attributeFrans Pop
Values below 1000 milli-celsius don't make sense and can cause the system to go into a thermal heart attack: the actual temperature will always be lower and thus the system will be throttled down to its lowest setting. An additional problem is that values below 1000 will show as 0 in /proc/acpi/thermal/TZx/trip_points:passive. cat passive 0 echo -n 90 >passive bash: echo: write error: Invalid argument echo -n 90000 >passive cat passive 90000 Signed-off-by: Frans Pop <elendil@planet.nl> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>

2009-11-05thermal: sysfs-api.txt - reformat for improved readabilityFrans Pop
The document currently uses large indentations which make the text too wide for easy readability. Also improve general consistency.
