You're using the passive-temp, critical-temp and force-shut-temp properties in your driver without declaring them here. But more importantly, please use the generic trip-points for this. I guess it shouldn't be a problem to introduce a "forced-shutdown" trippoint [0] for the additional trip-point you have - thermal maintainers, please shout if I'm wrong :-) Heiko [0] in a separate patch, changing - thermal_trip_type enum in include/linux/thermal.h - trip_types mapping in drivers/thermal/of-thermal.c - Documentation/devicetree/bindings/thermal/thermal.txt > + > +Example: > +tsadc: tsadc@ff280000 { > + compatible = "rockchip,rk3288-tsadc"; > + reg = <0xff280000 0x100>; > + interrupts = ; > + clocks = <&cru SCLK_TSADC>, <&cru PCLK_TSADC>; > + clock-names = "tsadc", "apb_pclk"; > +};
