Subject: [PATCH] dt-bindings: ata: snps,dwc-ahci: Allow 'iommus' property
Date: Wed, 22 Oct 2025 18:04:21 -0500 [thread overview]
Message-ID: <20251022230422.423230-1-robh@kernel.org> (raw)
The AMD Seattle DWC AHCI is behind an IOMMU and has 1-3 entries, so add
the 'iommus' property. There's not a specific compatible, so we can't
limit it to Seattle.
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
