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
