1	* Freescale General-purpose Timers Module
2	
3	Required properties:
4	  - compatible : should be
5	    "fsl,<chip>-gtm", "fsl,gtm" for SOC GTMs
6	    "fsl,<chip>-qe-gtm", "fsl,qe-gtm", "fsl,gtm" for QE GTMs
7	    "fsl,<chip>-cpm2-gtm", "fsl,cpm2-gtm", "fsl,gtm" for CPM2 GTMs
8	  - reg : should contain gtm registers location and length (0x40).
9	  - interrupts : should contain four interrupts.
10	  - interrupt-parent : interrupt source phandle.
11	  - clock-frequency : specifies the frequency driving the timer.
12	
13	Example:
14	
15	timer@500 {
16		compatible = "fsl,mpc8360-gtm", "fsl,gtm";
17		reg = <0x500 0x40>;
18		interrupts = <90 8 78 8 84 8 72 8>;
19		interrupt-parent = <&ipic>;
20		/* filled by u-boot */
21		clock-frequency = <0>;
22	};
23	
24	timer@440 {
25		compatible = "fsl,mpc8360-qe-gtm", "fsl,qe-gtm", "fsl,gtm";
26		reg = <0x440 0x40>;
27		interrupts = <12 13 14 15>;
28		interrupt-parent = <&qeic>;
29		/* filled by u-boot */
30		clock-frequency = <0>;
31	};
