From e75f8b666c976aff2aa30b967f74df021d800993 Mon Sep 17 00:00:00 2001 From: "Joe.C" <yingjoe.chen@mediatek.com> Date: Fri, 1 May 2015 15:43:30 +0800 Subject: [PATCH 43/76] ARM: dts: mt8127: enable basic SMP bringup for mt8127 Add arch timer node to enable arch-timer support. MT8127 firmware doesn't correctly setup arch-timer frequency and CNTVOFF, add properties to workaround this. This also set cpu enable-method to enable SMP.
