You don't clearly state whether your patch series keep compatibility with the 375 Z1 or not. And in fact, it doesn't keep compatibility with Z1. I'm fine with that, but then it means we should officially declare the Z1 support in mainline as dead, and get rid of the workarounds that applied only to 375 Z1.
