From 6a0d6733098965b8b58e8008e0fe1333d4f24953 Mon Sep 17 00:00:00 2001 From: kyrie wu Date: Wed, 8 Jun 2022 07:07:55 +0100 Subject: [PATCH] media: media: jpegenc: set bit mask for jpegenc 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.
