Subject: [PATCH v3 05/24] dt-bindings: memory: mediatek: Add domain definition
Date: Wed, 30 Sep 2020 15:06:28 +0800 [thread overview]
Message-ID: <20200930070647.10188-6-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200930070647.10188-1-yong.wu@mediatek.com>
In the latest SoC, there are several HW IP require a sepecial iova
range, mainly CCU and VPU has this requirement. Take CCU as a example,
CCU require its iova locate in the range(0x4000_0000 ~ 0x43ff_ffff).
In this patch we add a domain definition for the special port. In the
example of CCU, If we preassign CCU port in domain1, then iommu driver
will prepare a independent iommu domain of the special iova range for it,
then the iova got from dma_alloc_attrs(ccu-dev) will locate in its special
range.
This is a preparing patch for multi-domain support.
