Yeah, I understand the intention, but I have mixed feelings about this. OOH it helps with the cases like yours, OTO it sounds like a hack instead of proper implementation of the pin muxing. Yes, I know there are some drivers in the kernel do similar things, but it most likely historically and not always having the same HW capabilities as this chip. -- With Best Regards, Andy Shevchenko
