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 <[email protected]> Cc: Guodong Xu <[email protected]> Cc: Amit Pundir <[email protected]> Cc: YongQin Liu <[email protected]> Cc: John Youn <[email protected]> Cc: Minas Harutyunyan <[email protected]> Cc: Douglas Anderson <[email protected]> Cc: Chen Yu <[email protected]> Cc: Felipe Balbi <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> Cc: [email protected] 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
