Finally, I figured out it is the following patchset which can fix the issue. That is said
the issue disappears if these patches are applied to v4.0 kernel:

9a6d729 of: Calculate device DMA masks based on DT dma-range size
22b3c18 arm: dma-mapping: limit IOMMU mapping size
de335bb4 PCI: Update DMA configuration from DT
c49b8fc of/pci: Add of_pci_dma_configure() to update DMA configuration
6675a60 PCI: Add helper functions pci_get[put]_host_bridge_device()
0c79c81 of: Fix size when dma-range is not used
1f5c69a of: Move of_dma_configure() to device.c to help re-use
ed74862 of: iommu: Add ptr to OF node arg to of_iommu_configure()
