| description: | |
| 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. |
