I know the original authors aren't using the driver anymore and it took quite a bit of time until others started to contribute to it so I suspect the driver hasn't been in use for that long. There are no instances of the device in the in-kernel DTS either. Any DTS author should have also noticed the issue but of course there's a risk someone could have just changed the polarity and not bothered to chech what it was supposed to be. I agree the commit message should be more vocal about the effects on existing DTS. -- Kind regards, Sakari Ailus
