2020-06-29thermal: Explicitly enable non-changing thermal zone devicesAndrzej Pietrasiewicz1-0/+6
Some thermal zone devices never change their state, so they should be always enabled.

2015-08-03thermal: consistently use int for temperaturesSascha Hauer1-1/+1
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

2013-05-28Thermal: dove: Remove redundant use of of_match_ptrSachin Kamat1-1/+1
'dove_thermal_id_table' is always compiled in and the driver is dependent on OF. Hence use of of_match_ptr is unnecessary.

2013-03-11Thermal: dove: Convert to devm_ioremap_resource()Sachin Kamat1-10/+6
Use the newly introduced devm_ioremap_resource() instead of devm_request_and_ioremap() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages; so all explicit error messages can be removed from the failure code paths.
