2016-11-23thermal: tango: Fix module autoloadJavier Martinez Canillas1-0/+1
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/thermal/tango_thermal.ko | grep alias $ After this patch: $ modinfo drivers/thermal/tango_thermal.ko | grep alias alias: of:N*T*Csigma,smp8758-thermalC* alias: of:N*T*Csigma,smp8758-thermal Acked-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2016-09-27thermal: tango: add resume supportMarc Gonzalez1-2/+17
When this platform is suspended, firmware powers the entire SoC down, except a few hardware blocks waiting for wakeup events. There is no context to save for this particular block. Therefore, there is nothing useful for the driver to do on suspend; so we define a NULL suspend hook. On resume, the driver initializes the block exactly as is done in the probe callback.

2016-05-17thermal: add temperature sensor support for tango SoCMarc Gonzalez1-0/+111
The Tango thermal driver provides support for the primitive temperature sensor embedded in Tango chips since the SMP8758. This sensor only generates a 1-bit signal to indicate whether the die temperature exceeds a programmable threshold.
