* 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,
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
control registers, e.g. ANATOP on imx6q.
- fsl,tempmon-data : phandle pointer to fuse controller that contains TEMPMON
calibration data, e.g. OCOTP on imx6q. The details about calibration data
can be found in SoC Reference Manual.
Optional properties:
- clocks : thermal sensor's clock source.
Example:
tempmon {
compatible = "fsl,imx6q-tempmon";
fsl,tempmon = <&anatop>;
fsl,tempmon-data = <&ocotp>;
clocks = <&clks 172>;
};
