Subject: [PATCH v2 1/2] dt-bindings: iommu: arm,smmu-v3: Add SC8280XP compatible
Date: Sat, 09 Mar 2024 14:31:09 +0100	[thread overview]
Message-ID: <20231219-topic-8280_smmuv3-v2-1-c67bd3226687@linaro.org> (raw)
In-Reply-To: <20231219-topic-8280_smmuv3-v2-0-c67bd3226687@linaro.org>

The smmu-v3 binding currently doesn't differentiate the SoCs it's
implemented on. This is a poor design choice that may bite in the future,
should any quirks surface.

Add a compatible for the instance found on Qualcomm SC8280XP.
