[PATCH 1/2] ARM: mediatek: Add sysirq device node to mt6592 dtsi
From: Howard Chen
Date: Thu Jan 08 2015 - 01:22:44 EST
Add sysirq node to mt6592.dtsi and also correct timer interrupt flag.
The old setting works because boot loader already set it.
With a sysirq device node, the timer interrupt can use a correct value.
