Subject: [PATCH 00/21] MT8192 IOMMU support
Date: Sat, 11 Jul 2020 14:48:25 +0800	[thread overview]
Message-ID: <20200711064846.16007-1-yong.wu@mediatek.com> (raw)

This patch mainly adds support for mt8192 IOMMU and SMI.

mt8192 also is MTK IOMMU gen2 which uses ARM Short-Descriptor translation
table format. The M4U-SMI HW diagram is as below:

                          EMI
                           |
                          M4U
                           |
                      ------------
                       SMI Common
                      ------------
                           |
  +-------+------+------+----------------------+-------+
  |       |      |      |       ......         |       |
  |       |      |      |                      |       |
larb0   larb1  larb2  larb4     ......      larb19   larb20
disp0   disp1   mdp    vdec                   IPE      IPE

All the connections are HW fixed, SW can NOT adjust it.

Comparing with the preview SoC, this patchset also adds two functions:
a) add iova 34 bits support.
b) add multi domains support since several HW has the special iova
region requirement.

this patchset depend on v5.8-rc1 and mt6779 iommu[1].
