From e85e84d19b9dac3d3ac92c9f6a24d034691f1243 Mon Sep 17 00:00:00 2001 From: Tomasz Nowicki Date: Wed, 15 Jul 2020 09:06:48 +0200 Subject: [PATCH] dt-bindings: arm-smmu: add compatible string for Marvell Armada-AP806 SMMU-500 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.
