From mboxrd@z Thu Jan 1 00:00:00 1970 From: yingjoe.chen@mediatek.com (Yingjoe Chen) Date: Sat, 16 May 2015 15:58:30 +0800 Subject: [PATCH v2 9/9] ARM: dts: mt8127: enable basic SMP bringup for mt8127 In-Reply-To: <1431763110-443-1-git-send-email-yingjoe.chen@mediatek.com> References: <1431763110-443-1-git-send-email-yingjoe.chen@mediatek.com> Message-ID: <1431763110-443-10-git-send-email-yingjoe.chen@mediatek.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
