+Binding for Thermal Sensor driver for BCM2835 SoCs.
+
+Required parameters:
+-------------------
+
+compatible: 		should be one of: "brcm,bcm2835-thermal",
+			"brcm,bcm2836-thermal" or "brcm,bcm2837-thermal"
+reg:			Address range of the thermal registers.
+clocks: 		Phandle of the clock used by the thermal sensor.
+#thermal-sensor-cells:	should be 0 (see Documentation/devicetree/bindings/thermal/thermal-sensor.yaml)
+
+Example:
+
+thermal-zones {
+	cpu_thermal: cpu-thermal {
+		polling-delay-passive = <0>;
+		polling-delay = <1000>;
+
+		thermal-sensors = <&thermal>;
+
+		trips {
+			cpu-crit {
+				temperature	= <80000>;
+				hysteresis	= <0>;
+				type		= "critical";
+			};
+		};
+
+		coefficients = <(-538)	407000>;
+
+		cooling-maps {
+		};
+	};
+};
+
+thermal: thermal@7e212000 {
