The M4U in mt2712 is MTK's generation2 M4U which use the Short-descriptor like mt8173. The main difference is that there are 2 M4Us and 2 smi-commons in mt2712, while there is only 1 M4U and 1 smi-common in mt8173. The purpose is for balance the bandwidth. The mt2712 M4U-SMI HW diagram is as below: EMI | ------------------------------- | | M4U0 M4U1 | | smi-common0 smi-common1 | | ------------------------- -------------------- | | | | | | | | | | | | | | | | larb0 larb1 larb2 larb3 larb6 larb4 larb5 larb7 disp0 vdec cam venc jpg mdp1/disp1 mdp2/disp2 mdp3->larb names This patchset is based on v4.13-rc1, Also it base on Robin's[1], Honghui[2],Arvind[3]. Currently it don't contain the dtsi part as the ccf/power-domain has not been ready. The patch 1/2 adds the support of MT2712 IOMMU support, the patch 3/4 improve the m4u flow for mt2712, the last patch 5/6/7/8 mainly fix bug or improve code.
