Alexander Shishkin	f8c1376c22	usb: chipidea: remove unused field "regs" from ci13xxx ... The old implementation used global hw_bank, the new implementation uses udc-local hw_bank. This field seems to be a leftover from previous coding experiments.

Alexander Shishkin	5f36e231e9	usb: chipidea: add support for roles ... 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.

Alexander Shishkin	e443b33362	usb: chipidea: split the driver code into units ... Split the driver into the following parts: * core -- resources, register access, capabilities, etc; * udc -- device controller functionality; * debug -- logging events.
