-* Temperature Sensor on hisilicon SoCs
-
-** Required properties :
-
-- compatible: "hisilicon,tsensor".
-- reg: physical base address of thermal sensor and length of memory mapped
-  region.
-- interrupt: The interrupt number to the cpu. Defines the interrupt used
-  by /SOCTHERM/tsensor.
-- clock-names: Input clock name, should be 'thermal_clk'.
-- clocks: phandles for clock specified in "clock-names" property.
-- #thermal-sensor-cells: Should be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
