Oh, right, I remember now. Seems like there wasn't much consensus on how to solve the problem there, and I think I didn't really have time to work on it any more either. I think coupling in another driver to reset the device isn't a bad idea... this could even be usb3503 if you modified it a little, and it could also address Tomasz' concerns from that thread that the solution should be extensible to other HSIC devices that need a different reset sequence. But you need some mechanism to hook the two drivers together and make sure phy-samsung-usb2 synchronously calls the reset function at exactly the right point to ensure the timing works right. -- 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
