 - fsl,tempmon : phandle pointer to system controller that contains TEMPMON
   control registers, e.g. ANATOP on imx6q.
+- nvmem-cells: A phandle to the calibration cells provided by ocotp.
+- nvmem-cell-names: Should be "calib", "temp_grade".

+Deprecated properties:
 - 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.
 
+Direct access to OCOTP via fsl,tempmon-data is incorrect on some newer chips
+because it does not handle OCOTP clock requirements.

 Optional properties:
 - clocks : thermal sensor's clock source.
