Okay, I'll replace '(-1)' to THERMAL_NO_LIMIT and add the '#include' directive. --- Best Regards, Kunihiko Hayashi

Add nodes of thermal monitor and thermal zone for UniPhier LD20 SoC. The thermal monitor is included in sysctrl. Furthermore, since the reference board doesn't have a calibrated value of thermal monitor, this patch gives the default value for LD20 reference board.
