Subject: [PATCH v5 4/5] ARM: dts: mt8135: enable basic SMP bringup for mt8135
Date: Fri, 2 Oct 2015 23:19:40 +0800	[thread overview]
Message-ID: <1443799181-50409-5-git-send-email-yingjoe.chen@mediatek.com> (raw)
In-Reply-To: <1443799181-50409-1-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.
