Subject: [PATCH v5,3/6] media: mtk-vcodec: Support 34bits dma address for venc
Date: Sat, 5 Jun 2021 10:29:15 +0800	[thread overview]
Message-ID: <20210605022918.4213-4-irui.wang@mediatek.com> (raw)
In-Reply-To: <20210605022918.4213-1-irui.wang@mediatek.com>

Use the dma_set_mask_and_coherent helper to set venc
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 VENC actually locate, it
depends on the dma-ranges property of venc dtsi node.
