[PATCH v4] USB: add devicetree helpers for determining dr_mode and phy_type

[Sascha Hauer]

4th round of patches.

Peter, I would be glad if you could test them before your holiday. I rebased
your last round of Chipidea OTG patches onto this series which you can pull
here:

git://git.pengutronix.de/git/imx/linux-2.6.git tags/usb-chipidea-otg-for-next

I couldn't really test the otg patches since my current hardware does not have
the ID pin connected, but I can verify that my usecase still works with your
patches applied.

Alex, should the patches work for you and are fine otherwise, could you apply
them for v3.9?
