-* 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,r8a774a1-thermal" (RZ/G2M)
-			    - "renesas,r8a774b1-thermal" (RZ/G2N)
-			    - "renesas,r8a7795-thermal" (R-Car H3)
-			    - "renesas,r8a7796-thermal" (R-Car M3-W)
-			    - "renesas,r8a77961-thermal" (R-Car M3-W+)
-			    - "renesas,r8a77965-thermal" (R-Car M3-N)
-			    - "renesas,r8a77980-thermal" (R-Car V3H)
-- 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 (must be 3).
-- 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 0x100>,
-		      <0 0xe61a0000 0 0x100>,
-		      <0 0xe61a8000 0 0x100>;
-		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>;
-		#thermal-sensor-cells = <1>;
-	};
-
-	thermal-zones {
-		sensor_thermal1: sensor-thermal1 {
-			polling-delay-passive = <250>;
-			polling-delay = <1000>;
-			thermal-sensors = <&tsc 0>;
-
-			trips {
-				sensor1_crit: sensor1-crit {
-					temperature = <90000>;
-					hysteresis = <2000>;
-					type = "critical";
-				};
-			};
-		};
-	};
