2012-09-24Thermal: List thermal_instance in thermal_cooling_device.Zhang Rui2-1/+7
List thermal_instance in thermal_cooling_device so that cooling device can know the cooling state requirement of all the thermal instances. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Reviewed-by: Rafael J. Wysocki <rjw@sisk.pl> Reviewed-by: Eduardo Valentin <eduardo.valentin@ti.com>

This struct is used to describe the behavior for a thermal cooling device on a certain trip point for a certain thremal zone. thermal_cooling_device_instance is not accurate, as a cooling device can be used for more than one trip point in one thermal zone device.

2012-09-24Thermal: Introduce thermal_zone_trip_update()Zhang Rui2-29/+81
This function is used to update the cooling state of all the cooling devices that are bound to an active trip point. This will be used for passive cooling as well, in the future patches. as both active and passive cooling can share the same algorithm, which is 1. if the temperature is higher than a trip point, a. if the trend is THERMAL_TREND_RAISING, use higher cooling state for this trip point b. if the trend is THERMAL_TREND_DROPPING, use lower cooling state for this trip point 2. if the temperature is lower than a trip point, use lower cooling state for this trip point.

2012-09-24Thermal: Introduce .get_trend() callback.Zhang Rui3-2/+59
According to ACPI spec, tc1 and tc2 are used by OSPM to anticipate the temperature trends. We introduced the same concept to the generic thermal layer for passive cooling, but now it seems that these values are hard to be used on other platforms. So We introduce .get_trend() as a more general solution. For the platform thermal drivers that have their own way to anticipate the temperature trends, they should provide their own .get_trend() callback. Or else, we will calculate the temperature trends by simply comparing the current temperature and the cached previous temperature reading.

2012-09-24Thermal: Introduce cooling states range supportZhang Rui1-4/+21
As the active cooling devices can have multiple cooling states, we may want only several cooling states for a certain trip point, and other cooling states for other active trip points. To do this, we should be able to describe the cooling device behavior for a certain trip point, rather than for the entire thermal zone. And when updating thermal zone, we need to check the upper and lower limit to make sure the cooling device is set to the proper cooling state. Note that this patch will not bring any different behavior as upper limit is set to max_state and lower limit is set to 0 in this patch, for now. Next patch will set these to real values.
