+* 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>;
+ #thermal-sensor-cells = <1>;
+ status = "okay";
+ };
+
+ 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";
+ };
+ };
+ };
+ };
