USB: r8a66597-hcd: host controller driver for R8A66597
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.
