No, that is not normal.  The hardware I was using doesn't have the
TPS6507x interrupt pin connected, so I couldn't test that code path (and
thus didn't attempt to include it).  What hardware are you using?

Also, I didn't think the driver was locking out all other access to the
I2C bus.  I will enhance my test suite to check for that case.
