Subject: [PATCH v3 3/4] dt-bindings: arm-smmu: add compatible string for Marvell Armada-AP806 SMMU-500
Date: Thu, 2 Jul 2020 22:16:32 +0200 [thread overview]
Message-ID: <20200702201633.22693-4-tn@semihalf.com> (raw)
In-Reply-To: <20200702201633.22693-1-tn@semihalf.com>
Add specific compatible string for Marvell usage due to errata of
accessing 64bits registers of ARM SMMU, in AP806.
AP806 SoC uses the generic ARM-MMU500, and there's no specific
implementation of Marvell, this compatible is used for errata only.
