From 634f57df1f3b61cc1b1441762718a14da28c27f8 Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Tue, 3 May 2022 15:14:16 +0800 Subject: iommu/mediatek: Just move code position in hw_init No functional change too, prepare for mt8195 IOMMU support bank functions. Some global control settings are in bank0 while the other banks have their bank independent setting. Here only move the global control settings and the independent registers together.
