Subject: [PATCH v2 1/6] dt-bindings: iommu: sun50i: Add compatible for Allwinner D1
Date: Mon, 2 Jan 2023 19:08:58 -0600 [thread overview]
Message-ID: <20230103010903.11181-2-samuel@sholland.org> (raw)
In-Reply-To: <20230103010903.11181-1-samuel@sholland.org>
D1 contains an IOMMU similar to the one in the H6 SoC, but the D1
variant has no external reset signal.
Signed-off-by: Samuel Holland <samuel@sholland.org>

Changes in v2:
- Disallow the 'resets' property for the D1 variant
