+Mediatek MT6577, MT6572 and MT6589 Timers
+---------------------------------------
+
+Required properties:
+- compatible: Should be "mediatek,mt6577-timer"
+- reg: Should contain location and length for timers register.
+- clocks: Clocks driving the timer hardware. This list should include two
+       clocks. The order is system clock and as second clock the RTC clock.
+
+Examples:
+
+       timer@10008000 {
+               compatible = "mediatek,mt6577-timer";
+               reg = <0x10008000 0x80>;
+               interrupts = <GIC_SPI 113 IRQ_TYPE_LEVEL_LOW>;
+               clocks = <&system_clk>, <&rtc_clk>;
+       };
