+      The interrupt output of the controller, i.MX6Q has IRQ_HIGH which
+      will be triggered when temperature is higher than high threshold,
+      i.MX6SX and i.MX7S/D have two more IRQs than i.MX6Q, one is IRQ_LOW
+      and the other is IRQ_PANIC, when temperature is lower than low
+      threshold, IRQ_LOW will be triggered, when temperature is higher
+      than panic threshold, IRQ_PANIC will be triggered, and system can
+      be configured to auto reboot by SRC module for IRQ_PANIC. IRQ_HIGH,
+      IRQ_LOW and IRQ_PANIC share same interrupt output of controller.
