| 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 | - clock-frequency : specifies the frequency driving the timer. |
| 11 | |
| 12 | Example: |
| 13 | |
| 14 | timer@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 | |
| 23 | timer@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>; |
| 30 | }; |
