[PATCH v5 1/1] media: mediatek: jpeg: support 34bits
Jianhua Lin
jianhua.lin at mediatek.com
Wed Aug 7 06:08:35 PDT 2024
the iommu HW supported 34bits iova space(16GB),
but mediatek jpeg enc/dec driver still is 32bit,
then need to set the bit32/bit33 iova to jpeg HW.
Signed-off-by: Jianhua Lin <jianhua.lin at mediatek.com>
---
Changes compared with v4:
- remove all instances of '.support_34bit = false',
and keep only the true assignments.
