Subject[RFC PATCH V2 0/2] Add Unisoc iommu basic driver
Date
From: Chunyan Zhang <chunyan.zhang@unisoc.com>

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
iommu: add Unisoc iommu basic driver
