Add support for 2 TSC nodes of thermal. Signed-off-by: Duy Nguyen Signed-off-by: Geert Uytterhoeven Reviewed-by: Niklas Söderlund --- Tested on Renesas Gray Hawk Single with an R-Car V4M SoC that has unfortunately no calibration values fused. To be queued in renesas-devel for v6.10. Changes compared to the BSP: - Drop bogus interrupts property, as interrupts are routed to the ECM, - Change polling-delay from <0> to <1000> as interrupts are not supported. --- arch/arm64/boot/dts/renesas/r8a779h0.dtsi | 40 +++++++++++++++++++++++ 1 file changed, 40 insertions(+) diff --git a/arch/arm64/boot/dts/renesas/r8a779h0.dtsi b/arch/arm64/boot/dts/renesas/r8a779h0.dtsi index 11885729181bc903..a01929231e08fa30 100644 --- a/arch/arm64/boot/dts/renesas/r8a779h0.dtsi +++ b/arch/arm64/boot/dts/renesas/r8a779h0.dtsi @@ -318,6 +318,16 @@ sysc: system-controller@e6180000 { #power-domain-cells = <1>; }; + tsc: thermal@e6198000 { + compatible = "renesas,r8a779h0-thermal"; + reg = <0 0xe6198000 0 0x200>, + <0 0xe61a0000 0 0x200>; + clocks = <&cpg CPG_MOD 919>; + power-domains = <&sysc R8A779H0_PD_ALWAYS_ON>; + resets = <&cpg 919>; + #thermal-sensor-cells = <1>; + }; + i2c0: i2c@e6500000 { compatible = "renesas,i2c-r8a779h0", "renesas,rcar-gen4-i2c"; @@ -653,6 +663,36 @@ prr: chipid@fff00044 { }; }; + thermal-zones { + sensor_thermal_cr52: sensor1-thermal { + polling-delay-passive = <250>; + polling-delay = <1000>; + thermal-sensors = <&tsc 0>; + + trips { + sensor1_crit: sensor1-crit { + temperature = <120000>; + hysteresis = <1000>; + type = "critical"; + }; + }; + }; + + sensor_thermal_ca76: sensor2-thermal { + polling-delay-passive = <250>; + polling-delay = <1000>; + thermal-sensors = <&tsc 1>; + + trips { + sensor2_crit: sensor2-crit { + temperature = <120000>; + hysteresis = <1000>; + type = "critical"; + }; + }; + }; + }; + timer { compatible = "arm,armv8-timer"; interrupts-extended = <&gic GIC_PPI 13 IRQ_TYPE_LEVEL_LOW>,
