14 registers and XUSB IPFS registers.
15 - reg-names: Must contain the following entries:
19 - interrupts: Must contain the xHCI host interrupt and the mailbox interrupt.
20 - clocks: Must contain an entry for each entry in clock-names.
21 See ../clock/clock-bindings.txt for details.
22 - clock-names: Must include the following entries:
34 - resets: Must contain an entry for each entry in reset-names.
35 See ../reset/reset.txt for details.
36 - reset-names: Must include the following entries:
40 Note that xusb_src is the shared reset for xusb_{ss,hs,fs,falcon,host}_src.
41 - nvidia,xusb-padctl: phandle to the XUSB pad controller that is used to
42 configure the USB pads used by the XHCI controller
