This patchset adds MT8188 SMI support. MT8188, similar to mt8195, there are two SMI-common HW, one is for VDO(video output), the other is for VPP(video processing pipe). They connect with different SMI-larbs, then some setting(bus_sel) is different. The connection between SMI and MM IOMMU could be something like this: IOMMU(VDO) IOMMU(VPP) | | SMI_COMMON_VDO SMI_COMMON_VPP ---------------- ---------------- | | ... | | ... larb0 larb2 ... larb1 larb3 ... Another change is that the register about enable/disable iommu is in security world. We add some SMC command to set it. And we add a return value for configure port function because SMC call may fail. changes since v5: - base on tag: next-20220817. - return the result of config_port directly in mtk_smi_larb_resume(). - update the comments about flag MTK_SMI_FLAG_CFG_PORT_SEC_CTL. - put the code about CFG_PORT_SEC_CTL before SMI_LARB_NONSEC_CON. - remove the unnecessary type conversion of larb->mmu. changes since v4: - base on tag: next-20220728. - new patch[2/4] to add return value for all config port function. - rename enum IOMMU_ATF_CMD to a lower case: iommu_atf_cmd. - rename MTK_SMI_FLAG_SEC_REG to MTK_SMI_FLAG_CFG_PORT_SEC_CTL. - rename IOMMU_ATF_CMD_COUNT to IOMMU_ATF_CMD_MAX. - add some comment for why still need write SMI_LARB_NONSEC_CON. - return an error(-EINVAL) when enable iommu failed by SMC call. - put enum iommu_atf_cmd inside the macro CONFIG_MTK_SMI. changes since v3: - base on tag: next-20220726. - no code change just remove the change-id in patch [2/3]. changes since v2: - base on tag: next-20220722. - move some included header to the source file that use them. changes since v1: - base on tag: next-20220720. - adds MT8188 SMI support.
