Kuninori Morimoto c1e4877a41 usb: renesas_usbhs: modify device attach method
Current renesas_usbhs had been assigning udev to each urb.
It was executed even though it was device0.
For this reason, the device0 had to set the new device address
which has still not been assigned. (it will be assigned on next step).
Current renesas_usbhs used fixed address for it.
but it is not good for USB hub support.
This patch modifies this issue.

Michal Nazarewicz 7177aed44f usb: gadget: rename usb_gadget_driver::speed to max_speed
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”.  This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.

This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures.  All
of those represent the *maximal* speed given entity supports.

After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
  supports, and
* usb_composite_driver::max_speed - maximal speed composite
  gadget supports.

Felipe Balbi 193ab2a607 usb: gadget: allow multiple gadgets to be built
now that we have the udc class, we can allow
multiple gadget controller drivers to be
compiled as modules. This will allow for
distro-like kernels for embedded devices.

With this patch, I managed to build an x86
kernel with support for many of the controllers
enabled:

CONFIG_USB_FUSB300=m
CONFIG_USB_R8A66597=m
CONFIG_USB_M66592=m
CONFIG_USB_AMD5536UDC=m
CONFIG_USB_CI13XXX_PCI=m
CONFIG_USB_NET2272=m
CONFIG_USB_NET2280=m
CONFIG_USB_GOKU=m
CONFIG_USB_LANGWELL=m
CONFIG_USB_EG20T=m

Also an ARM kernel with support for many controllers:

CONFIG_USB_FUSB300=m
CONFIG_USB_OMAP=m
CONFIG_USB_R8A66597=m
CONFIG_USB_GADGET_MUSB_HDRC=m
CONFIG_USB_M66592=m
CONFIG_USB_NET2272=m
CONFIG_USB_DUMMY_HCD=m

The next step would be to get rid of the
direct access to arch/ and mach/ directories
on some gadget controllers so that we can
build all of them without depending on their
respective ARCH_* symbols.
