I can test this on msm8974 for you using a Nexus 5. Here's what I've
done so far:

The device tree nodes appear in sysfs:

/ # ls -1 /sys/class/thermal/
cooling_device0
cooling_device1
thermal_zone0
thermal_zone1
thermal_zone2
thermal_zone3
thermal_zone4
thermal_zone5
thermal_zone6
thermal_zone7
thermal_zone8
thermal_zone9

The various temperatures were in the upper 40s and I threw some work at
all four CPU cores to warm up the phone and watched the various
temperatures rise:

/ # for i in $(seq 0 9) ; do
> TYPE=$(cat /sys/class/thermal/thermal_zone$i/type)
> TEMP=$(cat /sys/class/thermal/thermal_zone$i/temp)
> echo "$TYPE = $TEMP"
> done
cpu-thermal0 = 66000
cpu-thermal1 = 66000
cpu-thermal2 = 66000
cpu-thermal3 = 66000
q6-dsp-thermal = 60000
modemtx-thermal = 57000
video-thermal = 61000
wlan-thermal = 65000
gpu-thermal-top = 61000
gpu-thermal-bottom = 59000

To test the interrupt support, I lowered all of the temperature trips to
51C but I'm not sure where to read that notification. I assume one of
the cooling devices or a governor should be started? Sorry but I haven't
done any work in the thermal subsystem yet and I'm short on time this
morning to investigate right now.
