Yup, I've been bitten by this before on other boards. Marking the wrong port as an EHCI port will result in 12 pads being put in the wrong mux-mode straight away, due to the padconf settings we do in usb-ehci.c. With 12-pads, there's a very high chance that you lose other functionality. The patch has my ack. Is there a link to the schematics somewhere, so the next time we see something like this, we can just use those as reference? - Anand -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
