I wanted to send out two patches we're using on the dwc2 driver in order to make HiKey function.
The first is seemingly just a bug fix we ran into when changing modes while the bus was auto-suspended. The second is a little more interesting as it works around a limitation of the the device in that it can't handle split transactions, so the usb speed but be lowered and raised manually when full-speed devices come and go. I wanted to send these out for further review and consideration. Changes in v2: * Fix build issue reported by kbuildbot * Rework to avoid using new dts entry suggested by RobH * Further tweaks from Chen Yu to try to address comments from John Youn * Further simplified logic Feedback would be greatly appreciated! thanks -john Cc: Wei Xu <xuw...@hisilicon.com> Cc: Guodong Xu <guodong...@linaro.org> Cc: Amit Pundir <amit.pun...@linaro.org> Cc: Rob Herring <robh...@kernel.org> Cc: John Youn <johny...@synopsys.com> Cc: Douglas Anderson <diand...@chromium.org> Cc: Greg Kroah-Hartman <gre...@linuxfoundation.org> Cc: linux-usb@vger.kernel.org Cc: Chen Yu <cheny...@huawei.com> Chen Yu (2): usb: dwc2: Force port resume on switching to device mode usb: dwc2: Add a quirk to allow speed negotiation for Hisilicon Hi6220 drivers/usb/dwc2/core.h | 6 ++++ drivers/usb/dwc2/hcd.c | 69 +++++++++++++++++++++++++++++++++++++++++++++ drivers/usb/dwc2/platform.c | 1 + 3 files changed, 76 insertions(+) -- 2.7.4 -- 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
