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 :-)

[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
