Subject: [RESEND PATCH 6/6] ARM: dts: mt6580: enable basic SMP bringup for mt6580
Date: Fri, 19 Jun 2015 02:01:21 +0800 [thread overview]
Message-ID: <1434650481-39421-7-git-send-email-scott.shu@mediatek.com> (raw)
In-Reply-To: <1434650481-39421-1-git-send-email-scott.shu@mediatek.com>
Add arch timer node to enable arch-timer support. MT6580 firmware
doesn't correctly setup arch-timer frequency and CNTVOFF, add
properties to workaround this.
This set cpu enable-method to enable SMP.
