0003 Required parameters:
0004 -------------------
0005
0006 compatible: should be one of: "brcm,bcm2835-thermal",
0007 "brcm,bcm2836-thermal" or "brcm,bcm2837-thermal"
0008 reg: Address range of the thermal registers.
0009 clocks: Phandle of the clock used by the thermal sensor.
0010 #thermal-sensor-cells: should be 0 (see Documentation/devicetree/bindings/thermal/thermal-sensor.yaml)
