Subject[PATCH 0/5] iommu/tegra-smmu: Adding PCI support and mappings debugfs node
This series of patches are some followup patches for tegra-smmu.

There are four parts:
1, PATCH-1 is a clean-up patch for the recently applied SWGROUP change.
2, PATCH-2 fixes a potential race condition
3, PATCH-3/4 adds PCI device support
4, PATCH-5 adds a debugfs node for phys<=>iova mappings

Each of the four parts is sort of functional independent, so we may
apply them separately or incrementally depending on the reviews.

Nicolin Chen (5):
iommu/tegra-smmu: Unwrap tegra_smmu_group_get
iommu/tegra-smmu: Expend mutex protection range
iommu/tegra-smmu: Use iommu_fwspec in .probe_/.attach_device()
iommu/tegra-smmu: Add PCI support
iommu/tegra-smmu: Add pagetable mappings to debugfs
