Would you happen to know what kernel driver is servicing this interrupt?
Also, when exactly in the PD discovery and mode entry process is this interrupt triggered?

We want to back out the HACK which causes the LPC driver to call the notifier chain on every interrupt.

I have 2 CLs (https://chromium-review.googlesource.com/q/hashtag:%22extcon-pd-notify%22+(s...)) that use the PD notifier mechanism, which is what will be used once extcon is removed.
