   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.

  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 };
