MediaTek IOMMU block diagram always like below: M4U | smi-common | ------------- | | ... | | larb1 larb2 | | vdec venc All the consumer connect with smi-larb, then connect with smi-common. When the consumer works, it should enable the smi-larb's power which also need enable the smi-common's power firstly. Thus, Firstly, use the device link connect the consumer and the smi-larbs. then add device link between the smi-larb and smi-common. After adding the device_link, then "mediatek,larb" property can be removed. the iommu consumer don't need call the mtk_smi_larb_get/put to enable the power and clock of smi-larb and smi-common. About the MM dt-binding/dtsi patches, I guess they should go together, thus I don't split them for each a MM module and each a SoC. Base on v5.14-rc1, and a jpeg[1] and mdp[2] patchset.
