    * Temperature Monitor (TEMPMON) on Freescale i.MX SoCs

    Required properties:
    -- compatible : "fsl,imx6q-tempmon" for i.MX6Q, "fsl,imx6sx-tempmon" for i.MX6SX.
    - i.MX6SX has two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
    +- compatible : "fsl,imx6q-tempmon" for i.MX6Q, "fsl,imx6sx-tempmon" for i.MX6SX,
    + "fsl,imx7-tempmon" for i.MX7S/D.
    + 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 below than low threshold, IRQ_LOW will be triggered, when temperature
    is higher than panic threshold, system will auto reboot by SRC module.
    - fsl,tempmon : phandle pointer to system controller that contains TEMPMON
