Hi all, There is a known issue that the USB code can't handle USB HUB's external pins well, in that case, it may cause some onboard USB HUBs can't work since their PHY's clock or reset pin needs to operate. The user reported this issue at below: http://www.spinics.net/lists/linux-usb/msg131502.html In this patch set, I add a generic onboard USB HUB driver to handle this problem, the external signals will be configured before usb controller's initialization, it much likes we did it at board code before. The user needs to add this generic hub node at dts or add releted platform data to support it. The udoo users, help to test please.
