+* 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>;
+       };
