Subject: [PATCH v2 3/5] iommu: dma: Use of_iommu_get_resv_regions()
Date: Fri, 23 Apr 2021 18:32:32 +0200	[thread overview]
Message-ID: <20210423163234.3651547-4-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210423163234.3651547-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

For device tree nodes, use the standard of_iommu_get_resv_regions()
implementation to obtain the reserved memory regions associated with a
device.
