     NVIDIA Tegra xHCI controller
     ============================
     
     The Tegra xHCI controller supports both USB2 and USB3 interfaces exposed by
     the Tegra XUSB pad controller.

      - Tegra186: "nvidia,tegra186-xusb"
    - reg: Must contain the base and length of the xHCI host registers, XUSB FPCI
      registers and XUSB IPFS registers.
    - reg-names: Must contain the following entries:
      - "hcd"
      - "fpci"
      - "ipfs"
    - interrupts: Must contain the xHCI host interrupt and the mailbox interrupt.
    - clocks: Must contain an entry for each entry in clock-names.

      used by the xHCI controller. This list must comprise of a specifier for the
      XUSBA and XUSBC power-domains. See ../power/power_domain.txt and
      ../arm/tegra/nvidia,tegra20-pmc.txt for details.
    - power-domain-names: A list of names that represent each of the specifiers in
      the 'power-domains' property. Must include 'xusb_ss' and 'xusb_host' which
      represent the power-domains XUSBA and XUSBC, respectively. See
      ../power/power_domain.txt for details.
