This shouldn't be an issue, as we define what they are..
&usb0 {
status = "okay";
dr_mode = "peripheral";
};
&usb1 {
status = "okay";
dr_mode = "host";
};
but just in-case we have a regression somewhere else, i'll push out a
test with otg disabled. (it's enabled in 3.14.x and we need it for the
x15)
