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

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