Subject: [RESEND V1,2/2] media: media: jpegenc: set bit mask for jpegenc
Date: Fri, 20 May 2022 16:59:10 +0800	[thread overview]
Message-ID: <20220520085910.28839-3-irui.wang@mediatek.com> (raw)
In-Reply-To: <20220520085910.28839-1-irui.wang@mediatek.com>

From: kyrie wu <kyrie.wu@mediatek.com>

set jpeg encode DMA bit mask to support 34bits
iova space(16GB) that the mt8186 iommu HW support.
Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G,
regarding which iova range jpgenc actually locate, it
depends on the dma-ranges property of vdec dtsi node.
