Files which are related can be distributed into separate directories. This patch moves the UDC drivers into a separate directory.

This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

Note, two are left using the DEVICE_ATTR() macro, as there is no DEVICE_ATTR_WO() in Linus's tree, that will happen after 3.12-rc1 is out, a follow-on patch will be sent then.

Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.
