Subject: [PATCH v3 29/33] iommu/mediatek: Change the domid to iova_region_id
Date: Thu, 23 Sep 2021 19:58:36 +0800 [thread overview]
Message-ID: <20210923115840.17813-30-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210923115840.17813-1-yong.wu@mediatek.com>
Prepare for adding bankid, also no functional change.
In the previous SoC, each a iova_region is a domain; In the multi-banks
case, each a bank is a domain, then the original function name
"mtk_iommu_get_domain_id" is not proper. Use "iova_region_id" instead of
"domain_id".
