Subject: [PATCH v3 8/8] ARM: dts: mt6580: enable basic SMP bringup for MT6580
Date: Tue, 4 Aug 2015 21:54:24 +0800 [thread overview]
Message-ID: <1438696464-59858-9-git-send-email-scott.shu@mediatek.com> (raw)
In-Reply-To: <1438696464-59858-1-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.
