+
+* 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>;
+ };
