+* Broadcom STB thermal management

+Thermal management core, provided by the AVS TMON hardware block.
+
+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 {
+		compatible = "brcm,avs-tmon-bcm7445", "brcm,avs-tmon";
+		reg = <0xf04d1500 0x28>;
+		interrupts = <0x6>;
+		interrupt-names = "tmon";
+		interrupt-parent = <&avs_host_l2_intc>;
+	};

   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.
+- 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

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