Changes in v4:
- Update the indentation for 'examples'.

- Link to v3: https://lore.kernel.org/all/71b58547-545e-4953-baa0-f3c6c8c3d2f9@kernel.org/

Changes in v3:
- Same as v2 

- Link to v2: https://lore.kernel.org/r/20240617-hisilicon-thermal-dt-bindings-conversion-v2-1-5eea9bc59c77@gmail.com

Changes in v2:
- Remove extra node in example.
- Use standard node name in example.
- Include additional defines from includes.
- Add reference to thermal-sensor.yaml.
- Remove redundant properties and comments.

- Link to v1: https://lore.kernel.org/all/20240613224204.185844-1-abdulrasaqolawani@gmail.com

-* 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.

-Example :
-
-for Hi6220:
-	tsensor: tsensor@0,f7030700 {
-		compatible = "hisilicon,tsensor";
-		reg = <0x0 0xf7030700 0x0 0x1000>;
-		interrupts = <0 7 0x4>;
-		clocks = <&sys_ctrl HI6220_TSENSOR_CLK>;
-		clock-names = "thermal_clk";
-		#thermal-sensor-cells = <1>;
-	}
