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).

Is there any specific reason why the driver do not use the INT > pin from the TPS6507x to free a little bit the I2C bus. 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.
