* Temperature Monitor (TEMPMON) on Freescale i.MX SoCs
|
||||
|
||||
Required properties:
|
||||
- compatible : "fsl,imx6q-thermal"
|
||||
- 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.
|
||||
|
||||
Example:
|
||||
|
||||
tempmon {
|
||||
compatible = "fsl,imx6q-tempmon";
|
||||
fsl,tempmon = <&anatop>;
|
||||
fsl,tempmon-data = <&ocotp>;
