From a9467d954226f1a513cfe789a3a39d8fc73b5d16 Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Mon, 21 Aug 2017 19:00:15 +0800 Subject: [PATCH] iommu/mediatek: Move MTK_M4U_TO_LARB/PORT into mtk_iommu.c The definition of MTK_M4U_TO_LARB and MTK_M4U_TO_PORT are shared by all the gen2 M4U HWs. Thus, Move them out from mt8173-larb-port.h, and put them into the c file.
