+* 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)
+- reg : Address range of the thermal registers.
+- clocks : Must contain a reference to the functional clock.
+- #thermal-sensor-cells : Please see ./thermal.txt
+
+Option properties:
+
+- interrupts : Use interrupt
+- 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 (non interrupt support):
+
+ tsc1: thermal@e6198000 {
+ compatible = "renesas,r8a7795-thermal";
+ reg = <0 0xe6198000 0 0x5c>;
+ clocks = <&cpg CPG_MOD 522>;
+ power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
+ #thermal-sensor-cells = <0>;
+ status = "okay";
+ };
+
+ thermal-zones {
+ sensor_thermal1: sensor-thermal1 {
+ polling-delay-passive = <250>;
+ polling-delay = <1000>;
+
+ /* sensor ID */
+ thermal-sensors = <&tsc1>;
+
+ trips {
+ sensor1_crit: sensor1-crit {
+ temperature = <90000>;
+ hysteresis = <2000>;
+ type = "critical";
+ };
+ };
+ };
+ };
+
+Example (interrupt support):
+
+ tsc1: thermal@e6198000 {
+ compatible = "renesas,r8a7795-thermal";
+ reg = <0 0xe6198000 0 0x5c>;
+ interrupts = <GIC_SPI 67 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cpg CPG_MOD 522>;
+ power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
+ #thermal-sensor-cells = <0>;
+ status = "okay";
+ };
+
+ thermal-zones {
+ sensor_thermal1: sensor-thermal1 {
+ polling-delay-passive = <250>;
+ polling-delay = <0>;
+
+ /* sensor ID */
+ thermal-sensors = <&tsc1>;
+
+ trips {
+ sensor1_crit: sensor1-crit {
+ temperature = <90000>;
