usb: move ci13xxx and related code to drivers/usb/chipidea Since chipidea is a dual role controller, it makes sense to move it to its own directory, where we can also have host, otg and platform code related to this controller. It also makes sense to break out the driver into several compilation units like udc, host, debugging code, etc. Firstly, let's move the udc and platform code to drivers/usb/chipidea.

usb: chipidea: fix and improve dependencies if usb host or gadget support is built as module Since commit "5e0aa49 usb: chipidea: use generic map/unmap routines", the udc part of the chipidea driver needs the generic usb gadget helper functions. If the chipidea driver with udc support is built into the kernel and usb gadget is built a module, the linking of the kernel fails with: drivers/built-in.o: In function `_hardware_dequeue': drivers/usb/chipidea/udc.c:527: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1269: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1821: undefined reference to `usb_del_gadget_udc' drivers/usb/chipidea/udc.c:443: undefined reference to `usb_gadget_map_request' drivers/usb/chipidea/udc.c:1774: undefined reference to `usb_add_gadget_udc' This patch changes the dependencies, so that udc support can only be activated if the linux gadget support (USB_GADGET) is builtin or both chipidea driver and USB_GADGET are modular. Same dependencies for the chipidea host support and the linux host side USB support (USB). While there, fix the indention of chipidea the help text.

usb: chipidea: improve kconfig 2.0 This patch provides a cleaner solution to the problem described in commit 20a677fd ("usb: chipidea: improve kconfig"). The goal to be achieved is to force USB_CHIPIDEA=m if either USB_EHCI_HCD=m or USB_GADGET=m. If both are 'y' USB_CHIPIDEA may be selected to be 'm' or 'y'. The old patch had the drawback, that USB_CHIPIDEA could be chosen as 'y' though USB_EHCI_HCD or USB_GADGET (or both) were 'm' leading to a situation where USB_CHIPIDEA_HOST or USB_CHIPIDEA_UDC vanished from the config options producing a compilable but dysfunctional driver.

Say Y here to enable device controller functionality of the
ChipIdea driver.
usb: chipidea: add host role This adds EHCI host support to the chipidea driver. We want it to be part of the hdrc driver and not a standalone (sub-)driver module, as the structure of ehci-hcd.c suggests, so for chipidea controller we hack it to not provide platform-related code, but only the ehci hcd. The ehci-platform driver won't work for us here too, because the controller uses the same registers for both device and host mode and also otg-related bits, so it's not really possible to put ehci registers into a separate resource. This is not a pretty solution, but the alternative is exporting symbols from the chipidea driver to a ehci-chipidea driver and doing all the module refcounting.
