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 a jpeg dtbing patchset[1] that already got the necessary R-b.
