* | staging: omap-thermal: improve conf data handling and initializationEduardo Valentin2012-09-112-8/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While registering the thermal zone, it is required to have the cooling devices already setup, so that the .bind callback can succeed. Due to that, the driver code needs to be reorganized so that we first setup the cooling devices then the zones. This way we cope with the right thermal framework initialization sequence. This patch changes the order of the thermal zone initialization, so that we create it only when the cooling devices are available. It also adds some defensive checks for the config data, so that the callbacks are ready for calls when the data is still not initialized.

* staging: omap-thermal: common code to expose driver to thermal frameworkEduardo Valentin2012-07-174-0/+482
| | | | | | | | | | | | | | | | | This patch has the common thermal framework support for OMAP bandgap driver. It includes the zone registration and unregistration, the cpu cooling and the trip definitions. The trips definition is essentially one trip for passive cooling using the generic cpu cooling device and another one for thermal shutdown. The cpu cooling device is built based on the existing cpu freq table. The build should be agnostic to omap version, but relies that cpufreq is up and running by the time the driver registers the cpu cooling, as it relies on the table walk api from cpufreq.

* staging: OMAP4+: thermal: introduce bandgap temperature sensorEduardo Valentin2012-07-176-0/+1663
In the System Control Module, OMAP supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. This patch provides a platform driver which expose this feature. It is moduled as a MFD child of the System Control Module core MFD driver. This driver provides only APIs to access the device properties, like temperature, thresholds and update rate.
