Kernel-4.18.0-80.el8_fsl,gt

  • Freescale General-purpose Timers Module

Required properties:

  • compatible : should be
    “fsl,-gtm”, “fsl,gtm” for SOC GTMs
    “fsl,-qe-gtm”, “fsl,qe-gtm”, “fsl,gtm” for QE GTMs
    “fsl,-cpm2-gtm”, “fsl,cpm2-gtm”, “fsl,gtm” for CPM2 GTMs
  • reg : should contain gtm registers location and length (0x40).
  • interrupts : should contain four interrupts.
  • interrupt-parent : interrupt source phandle.
  • clock-frequency : specifies the frequency driving the timer.

Example:

timer@500 {
compatible = “fsl,mpc8360-gtm”, “fsl,gtm”;
reg = <0x500 0x40>;
interrupts = <90 8 78 8 84 8 72 8>;
interrupt-parent = <&ipic>;
/* filled by u-boot */
clock-frequency = <0>;
};

timer@440 {
compatible = “fsl,mpc8360-qe-gtm”, “fsl,qe-gtm”, “fsl,gtm”;
reg = <0x440 0x40>;
interrupts = <12 13 14 15>;
interrupt-parent = <&qeic>;
/* filled by u-boot */
clock-frequency = <0>;
};
