+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.
+
+Example:
+
+thermal: thermal@7e212000 {
+        compatible = "brcm,bcm2835-thermal";
+        reg = <0x7e212000 0x8>;
+        clocks = <&clocks BCM2835_CLOCK_TSENS>;
+};
