+* 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>;
+ };

control registers, e.g. ANATOP on imx6q.
+- nvmem-cells: A phandle to the calibration cells provided by ocotp.

+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.
