a2c3d6902f usb: chipidea: permit driver bindings pass phy pointer
Sometimes, the driver bindings may know what phy they use.
For example, when using device tree, the usb controller may have a
phandler pointing to usb phy.

77c4400f2f USB: Chipidea: rename struct ci13xxx_udc_driver to struct ci13xxx_platform_data
This patch rename struct ci13xxx_udc_driver and var with the type.

ci13xxx_platform_data reflect it's passed from platfrom driver.

a756186b61 USB: CI13xxx: Use usb_put_hcd() on failure to drop HCD
Use usb_put_hcd() call instead of usb_remove_hcd() as that's the appropriate
call to drop hcd which failed registration.

eb70e5ab8f 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.
