USB: EHCI: Add a generic platform device driver This adds a generic driver for platform devices. It works like the PCI driver and is based on it. This is for devices which do not have an own bus but their EHCI controller works like a PCI controller. It will be used for the Broadcom bcma and ssb USB EHCI controller.

ehci-platform: add pre_setup() method to platform data Sometimes there is a need to initialize some non-standard registers mapped to the EHCI region before accessing the standard EHCI registers. Add pre_setup() method with 'struct usb_hcd *' parameter to be called just before ehci_setup() to the 'ehci-platform' driver's platform data for this purpose... While at it, add the missing incomplete declaration of 'struct platform_device' to <linux/usb/ehci_pdriver.h>... The patch has been tested on the Marzen and BOCK-W boards.

USB: EHCI: add no_io_watchdog platform_data parameter to ehci-platform Enhance the ehci-platform driver to also accept no_io_watchdog as a platform data parameter. When no_io_watchdog is set to 1, the ehci controller will set ehci->need_io_watchdog to 0. Since most EHCI controllers do need the I/O watchdog to be on, only let those which need it to turn the watchdog off. Make sure that we change need_io_watchdog after the call to ehci_setup() because ehci_setup() will unconditionnaly set need_io_watchdog to 1.

USB: ehci-platform: Support ehci reset after resume quirk The Rockchip rk3288 EHCI controller doesn't properly detect the case when a device is removed during suspend. Specifically, when usb resume from suspend, the EHCI controller maintaining the USB state (FLAG_CF is 1, Current Connect Status is 1), but a USB device (like a USB camera on rk3288) may have been disconnected actually. Let's add a quirk to force ehci to go into the usb_root_hub_lost_power() path and reset after resume. This should generally reset the whole controller and all ports and initialize everything cleanly again, and bring the devices back up. As part of this, rename the "hibernation" paramter of ehci_resume() to force_reset since hibernation is simply another case where we can't trust the autodetected status and need to force a reset of devices.

With removal of ehci-octeon and usage of ehci-platform ehci dma_mask is now limited to 32 bits (coerced in ehci_platform_probe).
