[PATCH 1/2] dt-bindings: usb: xhci: Allow "iommus" and "dr_mode" properties

[PATCH 1/2] dt-bindings: usb: xhci: Allow "iommus" and "dr_mode" properties

[Rob Herring (Arm)]

Allow "iommus" property as it's reasonable for any XHCI controller to be
behind an IOMMU. Allow "dr_mode" as an XHCI controller can be part of a
dual-role controller.

In particular, the Marvell Armada 8K XHCI controller uses both of these
properties.
