2	* ARM Global Timer
3		Cortex-A9 are often associated with a per-core Global timer.

5	** Timer node required properties:
6	
7	- compatible : should contain
8		     * "arm,cortex-a5-global-timer" for Cortex-A5 global timers.
9		     * "arm,cortex-a9-global-timer" for Cortex-A9 global
10		         timers or any compatible implementation. Note: driver
11		         supports versions r2p0 and above.
12	
13	- interrupts : One interrupt to each core
14	
15	- reg : Specify the base address and the size of the GT timer
16		register window.
17	
18	- clocks : Should be phandle to a clock.

22		timer@2c000600 {
23			compatible = "arm,cortex-a9-global-timer";
24			reg = <0x2c000600 0x20>;
25			interrupts = <1 13 0xf01>;
26			clocks = <&arm_periph_clk>;
