Subject[PATCH v1 0/2] Add Unisoc iommu basic driver
Date
From: Chunyan Zhang <chunyan.zhang@unisoc.com>

Changes since RFC v2:
* Addressed Robin's comments:
- Add COMPILE_TEST support;
- Use DMA allocator for PTE;
- Revised to avoid resource leak issue;
- Added ->iotlb_sync implemented;
- Moved iommu group allocation to probe;
- Changed some function names to make them sprd specific;
* Added support for more iommu instance;

Changes since RFC v1:
* Rebased on v5.11-rc1;
* Changed sprd-iommu to tristate;
* Removed check for args_count of iommu OF node, since there's no args
for sprd-iommu device node;
* Added another IP version (i.e. vau);
* Removed unnecessary configs selection from CONFIG_SPRD_IOMMU;
* Changed to get zeroed pages.

Chunyan Zhang (2):
dt-bindings: iommu: add bindings for sprd iommu
