Subject: [PATCH 0/4] Add system mmu support for Armada-806
Date: Mon, 15 Oct 2018 15:00:42 +0300 [thread overview]
Message-ID: <1539604846-21151-1-git-send-email-hannah@marvell.com> (raw)
From: Hanna Hawa <hannah@marvell.com>
This series add support for IOMMU for AP806, including workaround
for accessing ARM SMMU 64bit registers.
AP-806 can't access SMMU registers with 64bit width, this patches split
the readq/writeq for 32bit access, due to erratanum #582743.
Hanna Hawa (4):
iommu/arm-smmu: introduce wrapper for writeq/readq
iommu/arm-smmu: Workaround for Marvell Armada-AP806 SoC erratum
#582743
dt-bindings: iommu/arm,smmu: add compatible string for Marvell
arm64: dts: marvell: add smmu node for Armada-AP806
