+* Broadcom Stingray Thermal
+
+This binding describes thermal sensors that is part of Stingray SoCs.
+
+Required properties:
+- compatible : Must be "brcm,sr-thermal"
+- reg : memory where tmon data will be available.
+- brcm,tmon-mask: A one cell bit mask of valid TMON sources.
+                  Each bit represents single TMON source.
+- brcm,max-crit-temp: Maximum supported critical temperature.
+
+Example:
+	tmons {
+		compatible = "simple-bus";
+		#address-cells = <1>;
+		#size-cells = <1>;
+		ranges = <0x0 0x0 0x8f100000 0x100>;
+
+		tmon: thermal@0 {
+			compatible = "brcm,sr-thermal";
+			reg = <0 0x40>;
+			brcm,tmon-mask = <0x3f>;
+			brcm,max-crit-temp = <105000>;
+		};
+	};
