Yes, it is well working without cooling-{min,max}-state or cooling-{min,max}-level. I look for the some code to parse "cooling-{min,max}-state or cooling-{min,max}-level" in drivers/thermal/*. But, there are no any code to parse it. But, Documentation/devicetree/bindings/thermal/thermal.txt contains just the 'cooling-{min,max}-state. I think that there are mismatch between document and thermal core driver.
