Please feel free to comment on that patch. A few notes about that patch compared to this one: 1. Label is uart9, not uart2. No idea where the 2 came from. 2. No sleep pinconf states. For SPI they were definitely causing problems. When I looked deeper into it it became unclear to me what the point of all this remuxing is. Right now you are selecting the "sleep" state in the geni code for runtime PM but nothing (yet) is actually power gating the QUPs, so the pinmux isn't doing a whole lot. Even if you power gate the QUPs there shouldn't be any reason (that I'm aware of) to remux. -Doug -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
