Also updates the device-tree doc about how to enable SMMU by devicetree. This patch series depends on: - https://patchwork.freedesktop.org/series/58710/ - https://patchwork.freedesktop.org/series/59000/ - https://patchwork.freedesktop.org/series/59002/ - https://patchwork.freedesktop.org/series/61650/ Changes since v1: - Rebase to the patch in which convert dp_wait_cond() was changed to return -ETIMEDOUT and update d71_disconnect_iommu() to be consistent. - If connected IOMMU failed, set mdev->iommu as NULL. Changes since v2: - Correct the code flow by not returning -ETIMEDOUT if dp_wait_cond() returns zero in d71_connect_iommu().
