Subject: [PATCH v2 8/9] ARM: dts: mt8135: enable basic SMP bringup for mt8135
Date: Sat, 16 May 2015 15:58:29 +0800 [thread overview]
Message-ID: <1431763110-443-9-git-send-email-yingjoe.chen@mediatek.com> (raw)
In-Reply-To: <1431763110-443-1-git-send-email-yingjoe.chen@mediatek.com>
Add arch timer node to enable arch-timer support. MT8135 firmware
doesn't correctly setup arch-timer frequency and CNTVOFF, add
properties to workaround this.
This also set cpu enable-method to enable SMP.
