Subject: [PATCH v2, 11/14] media: mtk-vcodec: Support 34bits dma address for vdec
Date: Sat, 17 Jul 2021 16:12:30 +0800 [thread overview]
Message-ID: <20210717081233.7809-12-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20210717081233.7809-1-yunfei.dong@mediatek.com>
Use the dma_set_mask_and_coherent helper to set vdec
DMA bit mask to support 34bits iova space(16GB) that
the mt8192 iommu HW support.
Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G,
regarding which iova range VDEC actually locate, it
depends on the dma-ranges property of vdec dtsi node.
