2012-11-13staging: omap-thermal: fix context restore functionRadhesh Fadnis1-36/+21
In the context restore function, if the context is lost or not is being checked by the contents of the counter register. But this is logic hold good as long as counter reset value is zero, if the reset value is non-zero then above logic doesn't hold good. Hence removed checking of the register value and restoring the context.

2012-11-13staging: omap-thermal: remove freq_clip tableEduardo Valentin2-69/+3
The API exposed by cpu cooling does not need any freq clip table anymore. Now the cpu cooling device is smart enough to build its own table. For this reason, this patch removes all the code that is generating a freq clip table and also removes all references in data structures regarding freq clip table.

There was an error in check for the valid temperature in function temp_to_adc_conversion. The temperature value was compared with higher limit for less than condition as well, resulting in returning -EINVAL. Corrected the check condition to properly check for lower and higher temperature limits.

2012-09-11staging: omap-thermal: improve conf data handling and initializationEduardo Valentin2-8/+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.

2012-07-16staging: omap-thermal: common code to expose driver to thermal frameworkEduardo Valentin4-0/+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.

2012-07-16staging: OMAP4+: thermal: introduce bandgap temperature sensorEduardo Valentin6-0/+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.
