Subject: media: media: jpegenc: set bit mask for jpegenc
Author: kyrie wu <kyrie...@mediatek.com>
Date: Wed Jun 8 07:07:55 2022 +0100
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.
