I think what Felipe meant was to only combine the gadget driver code into one patch. The series could be split into 6 patches like so. -dt binding -pci glue -core driver -host driver -gadget driver -drd driver > 19 files changed, 6065 insertions(+) > create mode 100644 drivers/usb/cdns3/Kconfig > create mode 100644 drivers/usb/cdns3/Makefile > create mode 100644 drivers/usb/cdns3/cdns3-pci-wrap.c > create mode 100644 drivers/usb/cdns3/core.c > create mode 100644 drivers/usb/cdns3/core.h > create mode 100644 drivers/usb/cdns3/debug.h > create mode 100644 drivers/usb/cdns3/debugfs.c > create mode 100644 drivers/usb/cdns3/drd.c > create mode 100644 drivers/usb/cdns3/drd.h > create mode 100644 drivers/usb/cdns3/ep0.c > create mode 100644 drivers/usb/cdns3/gadget-export.h > create mode 100644 drivers/usb/cdns3/gadget.c > create mode 100644 drivers/usb/cdns3/gadget.h > create mode 100644 drivers/usb/cdns3/host-export.h > create mode 100644 drivers/usb/cdns3/host.c > create mode 100644 drivers/usb/cdns3/trace.c > create mode 100644 drivers/usb/cdns3/trace.h > <snip> cheers, -roger -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
