Hi Kishon, I've been debugging why some devices do not work with the musb otg controller found on Allwinner SoC-s, and the conclusion is not good, the Android kernel does a poke to the phy before releasing the usb reset.
Now you did not want me to introduce any sunxi specific / private phy functions in my initial patch-series for adding sunxi support, but in this case I do not really see an alternative, as this is a very platform specific hack to work around an issue with the phy-s squelch detection which causes it to see a squelch when reset is released switching it to high speed mode when a lo speed device is connected, after which things fall apart. I'm open to some generic solution for this, but I do not see one myself. Thanks & Regards, Hans p.s. A review of my existing sun4i-usb-phy otg support work would be appreciated, this squelch thing is best left as a fix on top. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
