* Broadcom STB thermal management



Thermal management core, provided by the AVS TMON hardware block.



Required properties:

- compatible: must be one of:

	"brcm,avs-tmon-bcm7216"

	"brcm,avs-tmon-bcm7445"

	"brcm,avs-tmon"

- reg: address range for the AVS TMON registers

- interrupts: temperature monitor interrupt, for high/low threshold triggers,

	      required except for "brcm,avs-tmon-bcm7216"

- interrupt-names: should be "tmon"



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>;

	};
