+* ARM Global Timer
+ Cortex-A9 are often associated with a per-core Global timer.
+
+** Timer node required properties:
+
+- compatible : Should be "arm,cortex-a9-global-timer"
+ 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>;
+ };

+Marvell Orion SoC timer
+
+Required properties:
+- compatible: shall be "marvell,orion-timer"
+- reg: base address of the timer register starting with TIMERS CONTROL register
+- interrupt-parent: phandle of the bridge interrupt controller
+- interrupts: should contain the interrupts for Timer0 and Timer1
+- clocks: phandle of timer reference clock (tclk)
+
+Example:
+ timer: timer {
+ compatible = "marvell,orion-timer";
+ reg = <0x20300 0x20>;
+ interrupt-parent = <&bridge_intc>;
+ interrupts = <1>, <2>;
+ clocks = <&core_clk 0>;
