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 <[email protected]> Cc: Guodong Xu <[email protected]> Cc: Amit Pundir <[email protected]> Cc: Rob Herring <[email protected]> Cc: John Youn <[email protected]> Cc: Douglas Anderson <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> Cc: [email protected] Cc: Chen Yu <[email protected]> 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
