Thanks. I was hoping that would be the case given all your effort
getting Nexus 5 supported. :-)

Looks good. What are the contents of the files inside the two
cooling_device directories? The output of the following command would
be nice:
$ grep "" cooling_device?/*

For now, just checking if the tsens interrupt in /proc/interrupts
fires should be fine. I have another patch to add some information to
debugs that I'll send at some point.
How well does cpufreq work on 8974? I haven't looked at it yet but
we'll need it for thermal throttling.
