+Required properties:
+- compatible: must be "brcm,avs-tmon" and/or "brcm,avs-tmon-bcm7445"
+- reg: address range for the AVS TMON registers
+- interrupts: temperature monitor interrupt, for high/low threshold triggers
+- interrupt-names: should be "tmon"
+- interrupt-parent: the parent interrupt controller

+Example:
+
+	thermal@f04d1500 {

 - 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.

+Deprecated properties:

   can be found in SoC Reference Manual.
 
+Direct access to OCOTP via fsl,tempmon-data is incorrect on some newer chips
