1* Freescale General-purpose Timers Module
2
3Required 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 - clock-frequency : specifies the frequency driving the timer.

13
14timer@500 {
15 compatible = "fsl,mpc8360-gtm", "fsl,gtm";
16 reg = <0x500 0x40>;
17 interrupts = <90 8 78 8 84 8 72 8>;
18 interrupt-parent = <&ipic>;
19 /* filled by u-boot */
20 clock-frequency = <0>;
21};
22
23timer@440 {
24 compatible = "fsl,mpc8360-qe-gtm", "fsl,qe-gtm", "fsl,gtm";
25 reg = <0x440 0x40>;
26 interrupts = <12 13 14 15>;
27 interrupt-parent = <&qeic>;
28 /* filled by u-boot */
29 clock-frequency = <0>;
