-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>;
