2012-07-09usb: chipidea: permit driver bindings pass phy pointerRichard Zhao
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.

2012-07-09USB: Chipidea: add unified ci13xxx_{add,remove}_device for platform driversRichard Zhao
Platform drivers do the similar things to add/remove ci13xxx device, so create a unified one.

2012-05-11usb: chipidea: add host roleAlexander Shishkin
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.

2012-05-11usb: chipidea: add support for rolesAlexander Shishkin
Add some generic code for roles and implement simple role switching based on ID pin state and/or a sysfs file. At this, we also rename the device to ci_hdrc, which is what it is. The "manual" switch is made into a sysfs file and not debugfs, because it might be useful even in non-debug context. For some boards, like sheevaplug, it seems to be the only way to switch roles without modifying the hardware, since the ID pin is always grounded.
