From 829316b3bc897a3275a0354505fde3ccd0053936 Mon Sep 17 00:00:00 2001 From: Chao Hao Date: Fri, 3 Jul 2020 12:41:25 +0800 Subject: [PATCH] iommu/mediatek: Extend protect pa alignment value Starting with mt6779, iommu needs to extend to 256 bytes from 128 bytes which can send the max number of data for memory protection pa alignment. So we can use a separate patch to modify it.
