Hi Hanjun,

Thank you for your patch set. I have tested this patch set. This patch set is correct and solves the problem of Feiteng IOMMU.

------------------------------------------------------------------

Extended the SMMU_BYPASS_DEV to support SMMU default bypass for some CPU SoCs
which the SMMU is not functional well in address translation mode.

This is the version for 4.19 kernel. Guo Hui, if you didn't test patchset
based on 1.0 LTS kernel, you can just apply this patch set instead.

Thanks!
