Subject: media: hantro: Set DMA max segment size
Author: Francois Buergisser <fbuergisser@xxxxxxxxxxxx>
Date: Thu Jul 25 10:17:50 2019 -0400
The Hantro codec is typically used in platforms with an IOMMU,
so we need to set a proper DMA segment size. Devices without an
IOMMU will still fallback to default 64KiB segments.
