thermal: sysfs: Add a new sysfs node emul_temp for thermal emulation

2013-02-06T05:45:42+00:00

This patch adds support to set the emulated temperature method in
thermal zone (sensor). After setting this feature thermal zone may
report this temperature and not the actual temperature. The emulation
implementation may be based on sensor capability through platform
specific handler or pure software emulation if no platform handler defined.

This is useful in debugging different temperature threshold and its
associated cooling action. Critical threshold's cannot be emulated.
Writing 0 on this node should disable emulation.

thermal: Use thermal zone device id in netlink messages

2013-01-16T02:46:46+00:00

This patch changes the function thermal_generate_netlink_event
to receive a thermal zone device instead of a originator id.

This way, the messages will always be bound to a thermal zone.

Introduce THERMAL_TREND_RAISE_FULL and THERMAL_TREND_DROP_FULL

2013-01-04T07:22:36+00:00

These two new thermal_trend types are used to tell the governor
that the temeprature is raising/dropping quickly.

Thermal cooling governors should handle this situation and make
proper decisions, e.g. set cooling state to upper/lower limit directly
instead of one step each time.

Thermal: Fix DEFAULT_THERMAL_GOVERNOR

2012-12-12T07:34:48+00:00

Fix DEFAULT_THERMAL_GOVERNOR to be consistant with the
default governor selected in kernel config file.

Thermal: Add a notification API

2012-11-05T06:00:08+00:00

This patch adds a notification API which the sensor drivers'
can use to notify the framework. The framework then takes
care of the throttling according to the configured policy.

Thermal: Make thermal_cdev_update as a global function

2012-11-05T06:00:06+00:00

This patch makes the thermal_cdev_update function as a
global one, so that other files can use it. This function
serves as a single arbitrator to set the state of a cooling
device.

Thermal: Add thermal governor registration APIs

2012-11-05T06:00:05+00:00

This patch creates a structure to hold platform
thermal governor information, and provides APIs
for individual thermal governors to register/unregister
with the Thermal framework.

Thermal: Pass zone parameters as argument to tzd_register

2012-11-05T05:59:57+00:00

This patch adds the thermal zone parameter as an argument to
the tzd_register() function call; and updates other drivers
using this function.

Thermal: Add platform level information to thermal.h

2012-11-05T05:56:32+00:00

This patch adds platform level information to thermal.h
by introducing two structures to hold:
 * bind parameters for a thermal zone,
 * zone level platform parameters

Thermal: Add get trend, get instance API's to thermal_sys

2012-11-05T05:56:32+00:00

This patch adds the following API's to thermal_sys.c, that
can be used by other Thermal drivers.
 * get_tz_trend: obtain the trend of the given thermal zone
 * get_thermal_instance: obtain the instance corresponding
   to the given tz, cdev and the trip point.
