So here are a few dwc2 fixes that I've been using with HiKey. I'm not totally sure these are all ideal, but they avoid edge case issues that we have been running into with switching between gadget mode and host mode. I'd guess the first two are potentially -stable material, and the last might be worth sending to -stable too, as its a relatively simple fix, but to my understanding the UDC state tracking has always been broken so its not really a regression. But still. I'd love to get some feedback on the patches and consideration to be merged upstream. thanks -john Cc: Wei Xu <xuwei5@xxxxxxxxxxxxx> Cc: Guodong Xu <guodong.xu@xxxxxxxxxx> Cc: Amit Pundir <amit.pundir@xxxxxxxxxx> Cc: YongQin Liu <yongqin.liu@xxxxxxxxxx> Cc: John Youn <johnyoun@xxxxxxxxxxxx> Cc: Minas Harutyunyan <Minas.Harutyunyan@xxxxxxxxxxxx> Cc: Douglas Anderson <dianders@xxxxxxxxxxxx> Cc: Chen Yu <chenyu56@xxxxxxxxxx> Cc: Felipe Balbi <felipe.balbi@xxxxxxxxxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Cc: linux-usb@xxxxxxxxxxxxxxx John Stultz (3): usb: dwc2: Improve gadget state disconnection handling usb: dwc2: Error out of dwc2_hsotg_ep_disable() if we're in host mode usb: dwc2: Fix UDC state tracking drivers/usb/dwc2/gadget.c | 7 +++++++ drivers/usb/dwc2/hcd.c | 8 ++++++-- 2 files changed, 13 insertions(+), 2 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
