This adds two little devicetree helper functions for determining the
dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from
the devicetree.

The properties and their values have been taken from the fsl-mph-dr driver.
This binding is also documented (though currently not used) for the tegra
ehci driver (Documentation/devicetree/bindings/usb/nvidia,tegra20-ehci.txt).
This is a first attempt to parse these bindings at a common place so that
others can make use of it.
Basically I want to know whether this binding is recommended for new drivers
since normally the devicetree uses '-' instead of '_', and maybe there are
other problems with it.
I need this binding for the chipidea driver. I suspect that the fsl-mph-dr
driver also really handles a chipidea core.
Should we agree on this I would convert the fsl-mph-dr driver to use these
helpers.

This file should ideally go into drivers/usb/phy/.
I originally wanted to do that, but the host/peripheral/otg property is
not phy specific. DO you still want to move it there?
I think then you can just move of_usb_get_phy_mode() to phy/of.c.
Then we can also move some functions defined in otg.c (specific to PHY
and dt) to phy/of.c.
Thanks
