1*c66ec88fSEmmanuel Vadot* OHCI controller, NXP ohci-nxp variant
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot- compatible: must be "nxp,ohci-nxp"
5*c66ec88fSEmmanuel Vadot- reg: physical base address of the controller and length of memory mapped
6*c66ec88fSEmmanuel Vadot  region.
7*c66ec88fSEmmanuel Vadot- interrupts: The OHCI interrupt
8*c66ec88fSEmmanuel Vadot- transceiver: phandle of the associated ISP1301 device - this is necessary for
9*c66ec88fSEmmanuel Vadot               the UDC controller for connecting to the USB physical layer
