As patches 1 to 9 have been acked by the USB sub-maintainers do you consider to take them? If not, do you expect a pull request? This email is also a mean to check that this series didn't slip through the cracks :) Thanks, Gregory > > Changes between v5 and v6: > > * Added Acked-by from Alan Stern on patch 5. > > * Added Acked-by from Mathias Nyman on patches 6 to 9. > > * Added Acked-by from Felipe Balbi on patch 7. > > * Removed the patches introducing the usb-cluster support using the > phy framework waiting for a cleaner implementation of it. > > Changes between v4 and v5: > > * Fixed a compile time problem when CONFIG_USB_XHCI_MVEBU was > disabled.
