+Thermal driver for MAX77620 Power management IC from Maxim Semiconductor.
+
+Maxim Semiconductor MAX77620 supports alarm interrupts when its
+die temperature crosses 120C and 140C. These threshold temperatures
+are not configurable. Device does not provide the real temperature
+of die other than just indicating whether temperature is above or
+below threshold level.
+
+Required properties:
+-------------------
+#thermal-sensor-cells:	Please refer <devicetree/bindings/thermal/thermal.txt>
+			for more details.
+			The value must be 0.
+
+For more details, please refer generic thermal DT binding document
+<devicetree/bindings/thermal/thermal.txt>.
+
+Please refer <devicetree/bindings/mfd/max77620.txt> for mfd DT binding
+document for the MAX77620.
