* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver

On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
sensors (THS) which are the analog circuits for measuring temperature (Tj)
inside the LSI.

Required properties:
- compatible		: "renesas,<soctype>-thermal",
			  Examples with soctypes are:
			    - "renesas,r8a7795-thermal" (R-Car H3)
			    - "renesas,r8a7796-thermal" (R-Car M3-W)
- reg			: Address ranges of the thermal registers. Each sensor
			  needs one address range. Sorting must be done in
			  increasing order according to datasheet, i.e.
			  TSC1, TSC2, ...
- clocks		: Must contain a reference to the functional clock.
- #thermal-sensor-cells : must be <1>.

Optional properties:

- interrupts           : interrupts routed to the TSC (3 for H3 and M3-W)
- power-domain		: Must contain a reference to the power domain. This
			  property is mandatory if the thermal sensor instance
			  is part of a controllable power domain.

Example:

	tsc: thermal@e6198000 {
		compatible = "renesas,r8a7795-thermal";
		reg = <0 0xe6198000 0 0x68>,
		      <0 0xe61a0000 0 0x5c>,
		      <0 0xe61a8000 0 0x5c>;
		interrupts = <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>,
			     <GIC_SPI 68 IRQ_TYPE_LEVEL_HIGH>,
			     <GIC_SPI 69 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&cpg CPG_MOD 522>;
		power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;

* ZTE zx2967 family Thermal

Required Properties:
- compatible: should be one of the following.
    * zte,zx296718-thermal
- reg: physical base address of the controller and length of memory mapped
    region.
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
- clock-names: "topcrm" for the topcrm clock.
	       "apb" for the apb clock.
- #thermal-sensor-cells: must be 0.

Please note: slope coefficient defined in thermal-zones section need to be
multiplied by 1000.

Example for tempsensor:

	tempsensor: tempsensor@148a000 {
		compatible = "zte,zx296718-thermal";
		reg = <0x0148a000 0x20>;
		clocks = <&topcrm TEMPSENSOR_GATE>, <&audiocrm AUDIO_TS_PCLK>;
		clock-names = "topcrm", "apb";
		#thermal-sensor-cells = <0>;
	};

Example for cooling device:

	cooling_dev: cooling_dev {
		cluster0_cooling_dev: cluster0-cooling-dev {
			#cooling-cells = <2>;
			cpumask = <0xf>;
			capacitance = <1500>;
