From 0954d61a59e3c014e52b8d938bc12dc5a2e4949c Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Thu, 7 Jan 2021 20:29:09 +0800 Subject: [PATCH] iommu/mediatek: Remove the tlb-ops for v7s Until now, we have already used the tlb operations from iommu framework, then the tlb operations for v7s can be removed. Correspondingly, Switch the paramenter "cookie" to the internal structure.
