* 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,-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 = , , ; 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"; }; }; }; };
