However that excludes support for USB on 85xx & QorIQ devices.  Use

Alan Stern 68aa95d5d4 EHCI: workaround for MosChip controller bug
This patch (as1489) works around a hardware bug in MosChip EHCI
controllers.  Evidently when one of these controllers increments the
frame-index register, it changes the three low-order bits (the
microframe counter) before changing the higher order bits (the frame
counter).  If the register is read at just the wrong time, the value
obtained is too low by 8.

When the appropriate quirk flag is set, we work around this problem by
reading the frame-index register a second time if the first value's
three low-order bits are all 0.  This gives the hardware a chance to
finish updating the register, yielding the correct value.

Matthew Garrett a8b43c00ef USB: Fix runtime wakeup on OHCI
At least some OHCI hardware (such as the MCP89) fails to flag any change
in the host status register or the port status registers when receiving
a remote wakeup while in D3 state. This results in the controller being
resumed but no device state change being noticed, at which point the
controller is put back to sleep again. Since there doesn't seem to be any
reliable way to identify the state change, just unconditionally resume the
hub. It'll be put back to sleep in the near future anyway if there are no
active devices attached to it.

Sarah Sharp 48e8236114 xHCI/USB: Make xHCI driver have a BOS descriptor.
To add USB 3.0 link power management (LPM), we need to know what the U1
and U2 exit latencies are for the xHCI host controller.  External USB 3.0
hubs report these values through the SuperSpeed Capabilities descriptor in
the BOS descriptor.  Make the USB 3.0 roothub for the xHCI host behave
like an external hub and return the BOS descriptors.

The U1 and U2 exit latencies will vary across each host controller, so we
need to dynamically fill those values in by reading the exit latencies out
of the xHC registers.  Make the roothub code in the USB core handle
hub_control() returning the length of the data copied.

This patch do the following things:

1. Add header and Copyright for marvell usb driver.
2. Add mv_usb.h in include/linux/platform_data, make the driver
   fits all the marvell platform using the same ChipIdea usb ip.
3. Some SOC may has mutiple clock sources, so let me define it
   in mv_usb_platform_data and give two helper functions named
   udc_clock_enable/udc_clock_disable to deal with the clocks.
4. Different SOCs will have some difference in PHY initialization,
   so we will remove file mv_udc_phy.c and add two funtions in
   mv_usb_platform_data, let the platform relative driver to realize it.
5. Rewrite probe function according to the modification list above. Find
   it will kernel panic when probe failed. The root cause is as follows:
	When probe failed, the error handle may call device_unregister()
	which in return will call gadget_release.In current code,
	gadget_release have two issues:
		1: the_controller is a NULL pointer.
		2: if we free udc here, then the following code in probe
		   will access NULL pointer.

Kuninori Morimoto 654c35ab5e usb: gadget: renesas_usbhs: disable auto paket start on usbhs_pkt_push()
Automatically packet start by usbhs_pkt_push() was useful.
But the pushed packet will be called twice
if new packet was pushed on usbhs_pkt :: done callback.
(1st is called by usbhs_pkt_push(), 2nd is called by usbhsf_pkt_handler())

This patch disables automatic packet start,
and clarified packet start timing.

Kuninori Morimoto b331872b85 usb: gadget: renesas_usbhs: move done callback to struct usbhs_pkt
transfer done function was registered in struct struct usbhs_pipe_info.
It was good for mod_gadget, but not good for mod_host.
This function move it to struct usbhs_pkt.
