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

55 Deprecated property, phandle pointer to fuse controller that contains
56 TEMPMON calibration data, e.g. OCOTP on imx6q. The details about
57 calibration data can be found in SoC Reference Manual.
