-NVIDIA Tegra xHCI controller
-============================
-
-The Tegra xHCI controller supports both USB2 and USB3 interfaces exposed by
-the Tegra XUSB pad controller.
-
-Required properties:
---------------------
-- compatible: Must be:
- - Tegra124: "nvidia,tegra124-xusb"
- - Tegra132: "nvidia,tegra132-xusb", "nvidia,tegra124-xusb"
- - Tegra210: "nvidia,tegra210-xusb"
- - 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.
- See ../clock/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
- - xusb_host
- - xusb_host_src
- - xusb_falcon_src

-
-For Tegra210 and Tegra186:
-- power-domains: A list of PM domain specifiers that reference each power-domain
- 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.
-
-Optional properties:
---------------------
-- phys: Must contain an entry for each entry in phy-names.
- See ../phy/phy-bindings.txt for details.
-- phy-names: Should include an entry for each PHY used by the controller. The
- following PHYs are available:
- - Tegra124: usb2-0, usb2-1, usb2-2, hsic-0, hsic-1, usb3-0, usb3-1
- - Tegra132: usb2-0, usb2-1, usb2-2, hsic-0, hsic-1, usb3-0, usb3-1
