[PATCH v4] dt-bindings: mediatek: Add binding for mt2712 IOMMU and SMI

2018-05-24 Thread Yong Wu
This patch adds decriptions for mt2712 IOMMU and SMI. In order to balance the bandwidth, mt2712 has two M4Us, two smi-commons, 10 smi-larbs. and mt2712 is also MTK IOMMU gen2 which uses ARM Short-Descriptor translation table format. The mt2712 M4U-SMI HW diagram is as below:
