+* ARM Global Timer
+       Cortex-A9 are often associated with a per-core Global timer.
+
+** Timer node required properties:
+
+- compatible : should contain
+            * "arm,cortex-a5-global-timer" for Cortex-A5 global timers.
+            * "arm,cortex-a9-global-timer" for Cortex-A9 global
+                timers or any compatible implementation. Note: driver
+                supports versions r2p0 and above.
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the GT timer
+       register window.
+
+- clocks : Should be phandle to a clock.
+
+Example:
+
+       timer@2c000600 {
+               compatible = "arm,cortex-a9-global-timer";
+               reg = <0x2c000600 0x20>;
+               interrupts = <1 13 0xf01>;
+               clocks = <&arm_periph_clk>;
+       };
