Subject: [PATCH 1/2] dt-bindings: usb: xhci: Allow "iommus" and "dr_mode" properties
Date: Fri, 19 Sep 2025 17:34:31 -0500 [thread overview]
Message-ID: <20250919223433.2399927-1-robh@kernel.org> (raw)
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.
