Yong Wu fc3734698a dt-bindings: mediatek: Add binding for mt8192 IOMMU ... This patch adds decriptions for mt8192 IOMMU and SMI. mt8192 also is MTK IOMMU gen2 which uses ARM Short-Descriptor translation table format. The M4U-SMI HW diagram is as below: EMI | M4U | ------------ SMI Common ------------ | +-------+------+------+----------------------+-------+ | | | | ...... | | | | | | | | larb0 larb1 larb2 larb4 ...... larb19 larb20 disp0 disp1 mdp vdec IPE IPE All the connections are HW fixed, SW can NOT adjust it. mt8192 M4U support 0~16GB iova range. we preassign different engines into different iova ranges: domain-id module iova-range larbs 0 disp 0 ~ 4G larb0/1 1 vcodec 4G ~ 8G larb4/5/7 2 cam/mdp 8G ~ 12G larb2/9/11/13/14/16/17/18/19/20 3 CCU0 0x4000_0000 ~ 0x43ff_ffff larb13: port 9/10 4 CCU1 0x4400_0000 ~ 0x47ff_ffff larb14: port 4/5 The iova range for CCU0/1(camera control unit) is HW requirement.
