Move DWC2 driver out of staging 



The DWC2 driver should now be in good enough shape to move out of
staging. I have stress tested it overnight on RPI running mass
storage and Ethernet transfers in parallel, and for several days
on our proprietary PCI-based platform.

TODO:

	- Dan Carpenter would like to see some cleanups to the microframe

	  scheduler code:

	  http://www.mail-archive.com/linux-usb@vger.kernel.org/msg26650.html



	- Should merge the NAK holdoff patch from Raspberry Pi

	  (http://marc.info/?l=linux-usb&m=137625067103833). But as it stands

	  that patch is incomplete, it needs more investigation to see if it

	  can be made to work for non-Raspberry Pi platforms that lack the

	  special FIQ interrupt that the Pi has. Without this patch, the driver

	  has a high interrupt rate (8K/sec).



	- The Raspberry Pi platform needs to have support for its FIQ interrupt

	  added, to get the same level of functionality as the downstream

	  driver. The raspberrypi.org developers have indicated they are

	  willing to help with that.



	- Some of the default driver parameters (see 'struct dwc2_core_params'

	  in core.h) won't work for many platforms. So DT attributes will need

	  to be added for some of these. But that can be done as-needed as new

	  platforms are added.



	- Eventually the driver should be merged with the s3c-hsotg peripheral

	  mode driver, so that both modes of operation can be supported with a

	  single driver. But I think that can wait till after the driver has

	  been moved to mainline.



	- After that, OTG support can be added. I'm not sure how much demand

	  there is for that, though, so I have that as a low priority.



Please send any patches for this driver to Paul Zimmerman <paulz@synopsys.com>

and Greg Kroah-Hartman <gregkh@linuxfoundation.org>. And please CC linux-usb

<linux-usb@vger.kernel.org> too.
