H A D | mtk_iommu_v1.c | 8bbe13f5 Fri May 15 03:08:43 CDT 2020 Yong Wu <yong.wu@mediatek.com> iommu/mediatek-v1: Add def_domain_type
The MediaTek V1 IOMMU is arm32 whose default domain type is IOMMU_DOMAIN_UNMANAGED. Add this to satisfy the bus_iommu_probe to enter "probe_finalize".
The iommu framework will create a iommu domain for each a device. But all the devices share a iommu domain here, thus we skip all the other domains in the "attach_device" except the domain we create internally with arm_iommu_create_mapping.
Also a minor change: in the attach_device, "data" always is not null. Remove "if (!data) return".
