No oscilloscope testing on my side to investigate the matter in depth,
so the polarities inversion is based on what you changed in the driver.

The idea is to change the register definitions to match what the hardware
appears to be doing (based on your good look at the oscilloscope) to avoid
the confusion of setting register fields that look contradictory.
It's just a rename and the behavior remains the same.
