Subject: [RFC PATCH V2 0/2] Add Unisoc iommu basic driver
Date: Fri, 8 Jan 2021 19:38:49 +0800 [thread overview]
Message-ID: <20210108113851.354947-1-zhang.lyra@gmail.com> (raw)
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.
