[PATCH 0/3] usb: chipidea: fix error handling and add dr_role property

Hello,

while hacking on the chipidea driver, I fixed the error path in
the udc part of the chipidea driver. Further I added the possibility
to limit the driver to host or device only mode. It's possible via
platformdata and device tree. For dt I selected the dr_role property
which is already used for other dual role usb drivers.

regards, Marc
