    I would like to submit Renesas R8A66597 USB HCD driver.
    
    R8A66597 is Renesas USB 2.0 host and peripheral combined
    controller device originally designed for embedded products.
    As a limitation of this device, it does not support externel
    hub more than 2 tier, and cannot communicate with a USB
    device more than 10. Then this device is not compatible with
    EHCI and/or OHCI, I wrote driver support patch based on
    sl811 code.
    
    This driver has the following unique specifications:
    - Implement transfer timeout to share one pipe with plural endpoint.
    - Detach detection of a USB device connected to externel hub.
    
    The driver has been tested external hub, usb-hdd, usb-cdrom,
    usb-speaker, mice, keyboard, and usbtest driver.
