Hi Marek, Stefano
This series is based on u-boot-usb/master branch. After this series, nitrogen6x works with tftpboot to transfer files over usb, and will recognize a usb stick in the OTG port.
This V5 has been rebased to the latest u-boot-usb/master branch and changed to address Marek comments.
The most noticeable change is the removal of ehci_hcd_init_after_reset using CONFIG_EHCI_HCD_INIT_AFTER_RESET instead.
Stefano, if you would you like to take the last 3 patches, you should apply "i.MX6Q/DLS: Add MX6_PAD_GPIO_1__USB_OTG_ID" from Eric Nelson first.
The patches are mostly independent, so if a patch has an issue, please feel free to skip it. An exception is 1/17 should be before 2/17 if Stefano's branch merges upstream first, otherwise nitrogen6x will get a build error.
Thanks
